My (Somewhat) Productive Trip

For about two decades, I’ve felt anxious when traveling. I always get the impression that some problem might arise at work and that the habits I try to maintain in my routine — such as exercising, reading, and studying — will end up being disrupted. On top of that, all the time spent on preparation, waiting, buses, Uber rides, and flights, combined with sleeping away from my own bed, eating irregularly and randomly, and dealing with an uncertain schedules, often leaves me more tired than I was before traveling.

On the other hand, traveling with family provides many moments of closeness and fun, and discovering new places is almost always an enriching experience.

On my most recent trip, I almost managed to balance both sides — fun and healthy habits — by using a variety of strategies, with mixed results. Let's check them.


Habit list/app. During the trip, I kept using the same app I normally use to track my habits: Loop. It’s very simple and free. You just take a quick look to see what needs to be done that day, and by the end of the trip it’s easy to get an overview of everything you accomplished.

Reading. My Kindle Paperwhite helped me a lot with this. I usually switch between two or three books at the same time, because sometimes I don’t have the patience to spend long hours on the same one. I mix fiction with nonfiction so I don’t get bored. The Kindle (or any other e-reader) lets you carry several books without adding weight to your luggage and, in some cases, it even fits in your pocket. That way, every tedious waiting moment turns into an opportunity to read. All I had to do was choose four or five books in advance (it's nice to have some extras knowing I might abandon one or two along the way).

Learning. Even if you’re learning in ways other than simply reading books, the Kindle can help, since it accepts documents sent by email (in fact, you can copy articles like this into a document and send them!). In addition, you can prepare as many apps, audiobooks, and podcasts on your phone as you find necessary. The idea is to travel already prepared, with resources organized beforehand, so you can take advantage of every free/boring moment as a learning opportunity.

I got a little carried away and downloaded more than 50 podcasts before traveling, but I only listened to two or three. In practice, when I’m out exploring, I prefer listening to the sounds of the place — and I recommend you do the same. The podcasts ended up being useful only during bus or plane rides (especially if you get motion sickness when trying to read while moving).

I guess I should mention the obvious fact that traveling to a country where you don’t speak the language could be a great incentive to learn it before you go, and practice while you’re there.

Nutrition. I brought a big container of whey protein. It takes up much more space than the Kindle, but it was very helpful when I didn’t feel like looking for a restaurant, and it also helped save some money. Since carbs are easy to find on practically any corner, whey turned out to be a practical solution for me — it helped control hunger and, as a result, reduced nervousness and the tendency to choose high-calorie foods, or just made me eat fewer slices of pizza.

Work. A large part of my work can be done online — maybe yours is similar (or, even better, maybe you don’t even need to think about work during your vacation!). For me, it was enough to bring a lightweight laptop and keep the most important apps ready. I didn’t even turn the device off; I just closed and opened the lid whenever I had to wait for someone to get ready or take a shower.

Exercise. At each hotel I visited, I looked for a gym. When there wasn’t one, I did push-ups, bodyweight squats, and other simple exercises. It’s perfectly possible to get a good workout using only your own body weight. Ideally, you should already be familiar with this type of training before traveling, but if not, it’s easy to find options on YouTube. On almost every day of the trip — no matter how many places we wanted to explore — there was at least half an hour to fit in a workout. When that wasn’t possible, I changed my mindset: carrying luggage stopped being an annoyance and became a way to stay active. Also, in practically every trip I end up walking a lot, which helps avoid a sedentary lifestyle.

Meditation. In this area, I wasn’t very successful. I don’t think I’m a great meditator — for me, reading four or five books is much easier than meditating for two hours, even if reading takes ten times longer. During the trip, I had several opportunities to meditate while waiting for transportation or in idle moments, but I found it extremely difficult to concentrate. Maybe I should have prepared some kind of guided meditation to make it easier. Well, maybe next time I’ll be able to take better advantage of those pauses. The little meditation I did manage to complete seemed to lower my fear of flights a bit, however!

Creativity/writing. Here too, I wasn’t very successful. I enjoy writing for this and other blogs, but I ended up not producing anything during the trip. Maybe it was the change of environment, the lack of habit, the smaller keyboard, or even my own lack of effort. Either way, I believe that a change of scenery can be inspiring in the long run — and at least it motivated me to write this post!

Mindset shift. I tried to turn every “struggle” into a challenge. The toughest “workout” I did during this period was pushing a stroller uphill for more than half an hour — but carrying heavy luggage counts too! When I had to skip two meals, I treated it as “my fasting practice” (always with moderation and hydration!). Waiting in lines became conscious breathing exercises. And when I skipped a workout, I considered it a deload period I had been postponing for a while. It’s a small psychological trick, but sometimes it works very well to keep your mood up in those situations.

Conscious packing. Think carefully about what you should bring and what you can leave behind. If you’re staying in a big city or already know what you’ll eat, the whey is probably unnecessary. Likewise, if you’ll have access to a computer or an internet café, you might not need to carry a laptop. The idea is to travel with the minimum necessary, without forgetting anything truly essential.

What NOT to do. Avoid using addictive and unhelpful apps like Instagram, TikTok, and YouTube Shorts. They drain your time, distract you from the trip you could be enjoying, and, in my experience, increase anxiety quite a bit. On the other hand, don’t set “goals” for your vacation if you can avoid it. The idea isn’t to turn the trip into more work, but to be prepared to enjoy idle moments in a productive and pleasant way. Also, you won’t miss out on discovering and enjoying a new and unique place just because you have a book in your pocket — it can be read anytime, even in the bathroom! And please, don’t force your kids, friends, or companions to adopt the same habits as you. Some people prefer to use vacations to completely “disconnect” from all routine commitments. It might even be your preference on some days or trips too.

The most important part of this experience wasn’t the books I read or the workouts I did, but rather the reduction of the anxiety and boredom I mentioned at the beginning of the article. In the end, that made the trip much more enjoyable and lighter than previous ones.

I hope these tips are useful for you. And if you have more ideas for my next trips, I’d be happy to hear them!

Precision beats power, timing beats speed

"He's powerful and he's fast, but precision beats power, timing beats speed."

This is what UFC fighter Conor McGregor said after knocking out the previous featherweight champion, José Aldo—a legendary fighter with a 25-1 record at the time—in only 13 seconds, ten years before this post. It was one of the quickest fights in the history of the UFC.

The application of this concept in fighting should be clear to most people, especially if they have any practice in martial arts. In boxing, this simply means "punching at the right place at the right time."

However, the philosophy that inspired these words could be useful in many different fields.


Precision Beats Power

This idea is akin to the "work smarter, not harder" motto. It emphasizes the importance of accuracy and efficiency over brute strength and hard work.

Similarly, the saying "If a man knows not to which port he sails, no wind is favorable," attributed to Seneca, highlights the significance of having clear goals. Or "measure twice, cut once" as carpenters say.

Too often, we blame ourselves for not doing enough, or exhaust ourselves doing too much. But our power is limited, and it must be applied in the right way to be truly effective, or it will be wasted.

In other words, knowing precisely what you want to achieve and how to achieve it is more important than merely making a significant effort.

Once you get you plans in order,  you can then apply yourself to make them come to fruition.

Timing Beats Speed

This is simply the same principle applied across time: do not rush your actions, but take them in the right moment.

In personal development, patience and constancy is key to achieve your goals. If you have never trained your body, a 24-hour workout will probably harm you, but spreading the same 24 hours over a month will certainly yield better results - and less pain.

In finance, some people believe you can "beat the market" by buying the perfect stock before anyone else. This is unlikely, and even if you do find the perfect stock for a great price, remember "the market can remain irrational longer than you can remain solvent".

With the right timing, even "wrong" decisions can work in your favor. A market bubble leaves lots of bankrupt investors, while a few get rich because they got out in the right time.

Conversely, you should not postpone important goals to unspecified dates. There is a cost to being too early but there is also a cost to being too late. Many people wait to marry or have children until they have the perfect job or financial situation, but this creates its own challenges. Likewise, a dream vacation might be better enjoyed when you're more healthy and youthful.

Remember that you are mortal. Find the right time, but do it before the bell rings.

Limitations

There are few downsides to precision, but there is such a thing as planning too much. You might never find the perfect moment or the perfect plan, and perfectionism might become a bigger hurdle then imprecision.

Once you know you're headed in the right direction, it might be better to get moving than to take yet another look at the map. In fitness and finance, some investment is almost always better than none. And even the smartest plan may require some hard work to function properly.

Practical advice

Get your priorities straight. Put your goals in the Eisenhower box before you start taking action. Read How Much Land Does a Man Require by Leo Tolstoy. You are not too late. The best time to begin is now. Do not postpone your actions when you know you are in the right direction.

About this blog

This blog is a collection of ideas and concepts I find useful for navigating the world. Ideas and concepts are living tools; they can be used to find solutions and combined to create new ones.

I believe that learning ideas and concepts is more important than memorizing facts. The recollection of facts has been revolutionized by technology to a point where knowing how to use this technology and understanding the reliability of your sources are more important than knowing the facts themselves, as facts are nearly infinite and readily available with a few clicks if you know where to look.

Ideas are more flexible than facts. If someone was born in 1999, they simply cannot physically exist in 1997. However, interesting concepts like the placebo effect, the Matthew principle, confirmation bias, opportunity cost, and the Pareto Principle can apply in many different ways, with various nuances, exceptions, limitations, and variations.

Ideas can be true or false; concepts can also be true or false, but some are just more or less useful.

In other words, concepts are not absolute. The placebo effect, for example, can be measured; it applies to some situations/diseases, but not others; it can work wonders for headaches but have limited effect on a broken finger; it has limitations (it cannot grow you a new hand); it can vary from person to person.


Some concepts will instantly give you a bit of peace of mind in specific circumstances. Knowing that imposter syndrome is common can ease your mind if you feel you're not up to a task, and understanding analysis paralysis will show you why you feel like you can't make the best choice. As always, consider the limitations: sometimes, there is a better choice, or you really need the help of an expert to solve a problem (see the Dunning-Kruger effect).

Unlike most facts, concepts that seem contradictory can both be useful. The mention of the Dunning-Kruger Effect and imposter syndrome in the paragraph above is an example.

Concepts and ideas can also apply across different fields. The birth date of Napoleon may be relevant only to history, but game theory can apply across multiple fields.

Even concepts that are mostly wrong or obsolete are useful - they let you know where other people are coming from, or how modern ideas came to be - and future developments may prove there is some truth to them after all (for example, Lamarckism is mostly debunked, but modern study of epigenetics etc. could give it some limited validity, according to Wikipedia). Of course, when you learn such concepts you must also learn WHY they are false.

Concepts can be learned and named for easy access. If you have a cool idea without a name, maybe we can name it to facilitate recollection and discussion. Learned concepts become your toolbox for understanding new ideas and facing reality. You can also use them to communicate more efficiently with other people that are familiar with these ideas.

Some concepts are more useful than others. While this is hard to measure, technology can help here too; for example, we could theoretically count the number of times a concept is discussed or referenced online, putting the most common concepts as "fundamental" to the understanding of all online discussion.

Most of the ideas discussed here are not new. Often, I'm discussing things I've seen somewhere else. In all cases, I'll share my sources so you can explore them in depth. Sometimes, I will explore (and name) my own concepts. In these cases, I'm quite sure somebody, somewhere may have discussed it before - so please let me know in the comments.

The main concepts that I want to communicate in this post are simply:

- Learning ideas concepts is useful to understand the world.
- These concepts often have names and hierarchy, with some being more important than others.
- This blog will discuss concepts that are useful for your understanding, plus other related subjects. 

I'll use some help from AI to proofread and improve my blog posts. If you ever use AI, it is important to learn its limits and dangers; this is a subject we may tackle somewhere down the road.

For now, I'll leave a small list of useful concepts, with links to Wikipedia. If you ever use Wikipedia, it is important to learn its limits and dangers; this is a subject we may tackle somewhere down the road. For now, I think these links are useful.

I suggest you read these even if you are already familiar with the concepts. It will certainly deepen your understanding of these subjects.

Please let me know if there are any interesting/important concepts we could add to this list!
