I started my career at 14 as a software engineer, and co-founded Vinted after 10 years, which grew from a team of 2 to 250+. It was not trivial and it was not easy, though very rewarding.

17 of the most useful razors (rules of thumb that simplify decisions): 1. Bezos' Razors: • If unsure what action to take, let your 80-year-old self make it. • If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison. 2. Skinner's Law: If procrastinating on an item, you only have 2 options: (a) Make the pain of not doing it greater than the pain of doing it. (b) Make the pleasure of doing it greater than the pleasure of not doing it. 3. Luck Razor: • If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line. 4. Bragging Razor: • If someone brags about their success or happiness, assume it’s half what they claim. • If someone downplays their success or happiness, assume it’s double what they claim. 5. Hofstadter’s Law: • It always takes longer than you expect, even when you take into account Hofstadter’s Law. Every project costs 2x as much and takes 3x as long - even when you factor this into your projections. 6. Elon's Law: • If you have a project, combat Hofstader's Law by setting a ridiculously ambitious deadline. Even if it takes 3x longer than the deadline, you're ahead of everyone else. Elon Musk missing his super human deadlines is a feature rather than a bug. 7. Naval's Razors: • If you have 2 choices to make and it's 50/50, take the path that’s more painful in the short term. • If a task is worth less than your ambitious hourly rate - outsource it, automate it or delete it. 8. Munger's Law: • Never allow yourself to have an opinion on a subject unless you can state the opposing argument better than the opposition can. Steelman Arguments > Strawman Arguments 9. Hitchen's Razor: • What can be asserted without evidence can be dismissed without evidence. 10. Newton's Flaming Laser Sword: • If something can be settled by experiment or observation, then it is not worthy of debate. UFC 1 >>> Decade long debates on the best martial arts 11. Joe Rogan's Razors: • If unsure what action to take - ask what the hero in the movie would do. • If you're intensely passionate about something and nobody around you is interested in it - assume the scale of the internet might help you find them. 12. Taleb's Surgeon: • If presented with two seemingly equal candidates for a role, pick the one with the least amount of charisma. The uncharismatic one has got there despite their lack of charisma. The charismatic one has got there with the aid of their charisma. 13. Discomfort Razor: • The more uncomfortable the activity, the more likely it will lead to growth. • The more comfortable the activity, the more likely it will lead to stagnation. 1000 uncomfortable hours > 10,000 comfortable hours 14. Checkhov's Gun: • When telling a story, if it's non-essential - don't include it. "If you say in the 1st chapter that there is a rifle hanging on the wall, in the 2nd or 3rd chapter it absolutely must go off. If it's not going to be fired, it shouldn't be hanging there." 15. Occam's Razor: • Simple assumptions are more likely to be correct than complex assumptions. Avoid Occam's Duct Tape: • Someone who approaches a problem with a ridiculously large number of assumptions. 16. Walt Disney's Rule: • If struggling to think clearly about a subject, draw it out. See picture. 17. Schwarzeneggers' Rule: • Never need to monetize your artistic pursuits. You won't have to sacrifice your inner joy and vision for a payday. Arnold made millions from property and D2C bodybuilding guides so he never had to say yes to acting gigs he didn't like. Collected by George Mack (https://twitter.com/george__mack) Pircture: Walt Disney's drawing he made in 1957 of the Media Empire he wanted to build. It's iconic.

A few days ago I spoke to a friend I haven't seen for a few years. She wants to found a tech company and looks into different categories, like well-being, learning, and food. She wanted me to suggest which category has the biggest opportunity. Each category she looks in, she finds more questions than answers. Also, people from each category say that the category is hard. I said that, of course, it is hard to start and create something new in any category. It is hard because you always have more questions than answers initially, and you need to find those answers somehow. Many answers are possible to find only by trying and failing, not by researching or thinking. And failing is hard, yet necessary for success. There is no self-evident & clear new biggest opportunity in any category. Instead of looking for that, just pick the idea/concept, you believe the most and start doing it without knowing everything in advance. And first thing in doing is to find your first believers who will be your future partners. You can find them easier if you have committed yourself to a specific idea. In that case, speak to people and invite them to join your journey and see what will happen. Good luck with founding your new company! Photo: I made it in Italy a few weeks ago. P.S. This is my first insight posted from Qoorio web (not app).

I like this attitude: many answers can be found only by trying & failing. however it is not smth we learn at school. It's interesting how start-ups saw 2020- it was a good year, because they are used to challenges at an ongoing basis
