Worth checking your stock trading skills

Congratulations on your success! A few questions that came to mind (I don't expect you to answer all of them):

  • What did you give up to pursue trading full time?
  • How much capital did you start with? (6x is not enough to get to the size of a small hedge-fund if you start out with 50k...)
  • Do you use leverage?
  • Do you manage other investors' assets or only your own?
  • Have you automated portions of your trading routine?
  • Do you base your buy / sell decisions on value alone or do you use technical analysis? If so, which concepts do you find most useful?
  • How much do you invest in cryptocurrencies?

I liked tip 7 the most. Reminds me of a quote from a chessmaster (Maurice Ashley): "The most important insight in chess is that the other person is more important than you are"

Is Success the Enemy of Freedom? (Full)

Strong upvote. Success doesn't limit us. Success changes us. It is what we become that limits us.

Being Productive With Chronic Health Conditions

For me, I have found a microadjustment to your microadjustment helpful: Instead of drinking a whole cup of coffee, which causes unnecessary stress and heart racing for me, I only drink about 1/8th of a cup or even less at the same concentration. I have found that while this still has strong positive effects (more motivation, higher focus), it avoids most of the negative effects -- especially if it's taken in the morning.

Being Productive With Chronic Health Conditions

Thank you for this post. The personal experience certainly seeps through in your recommendations (which is a good thing).

I would like to mention another area: nutrition. A good chunk of your productivity depends on how well you eat. It also affects how well your body can fight the chronic condition. It also gives you another variable to play around with (do I feel better if I eat carbs?).

However, I don't think it is as simple as "eat your veggies". People with chronic illness should have a solid understanding of the nutrients the body needs to function properly (for example, the role of protein is often underestimated). They should also set up systems that allow them to fulfill these requirements in a quick and effective manner, without spending too much time and energy (e.g. through supplements, protein shakes, cooking in bulk). It is also wise to experiment with different diets and observe their effects on one's health (e.g. ketogenic, raw, protein-heavy).

One caveat though: it is easy to get caught up in optimizing nutrition and delude oneself into thinking that the next supplement will lead to a breakthrough. But it is important to get the fundamentals right.

Explaining Visual Thinking

Do you visualize the icosahedron as one object or do you split it up and consider each separately, but reminding oneself that it is actually one object?

My answer to your visual thinking riddle is: breath in through your mouth and breath out through mouth + nostrils. But I can't decipher your anagram!

Explaining Visual Thinking

First of all, if you can solve it without visualization, I think that this is preferable, precisely because it is faster. There is no need to force oneself to visualize everything.

To visualize something, you need to create a map from the formal domain you are studying to visual transformations. In other words, you need to understand "what the formula" mean (or at least one way of looking at them). Do you know what it means visually to multiply one complex number to another? If you don't, you will be stuck doing calculations. If you do, then you can visualize it and quickly come up with the solution.

From my experience, some people naturally tend towards visual thinking, while others don't. But if you consistently try to apply it, it will become natural at some point (it may take some time, don't give up prematurely).

One area where a lot of visual thinking is necessary, but that is relatively easy to visualize, is graph theory. Try to prove that a (connected undirected) graph has an Eulerian cycle (i.e. a cycle that contains every edge exactly once) if and only if all of its vertices have even degree.

Explaining Visual Thinking

Say you have two distinct points x and y. Consider all points whose distance to x is the same as to y. What can you say about the location of these points in terms of the line connecting x and y?

Try to solve any geometry puzzle with only your mind and you will be forced to do visual thinking.

Two explanations for variation in human abilities

I really appreciate you looking this up. Now it is clear that these claims are controversial.

Nevertheless, the question still is what learning ability refers to: Is it the ability to comprehend learning material that explains the topic well, or is it the ability to come up with the simple explanations yourself? It seems that the OP refers to the latter. The first kind probably has lower variation. Also, this means that when measuring learning ability, you should ensure that all involved people have access to the same "source". I would be interested in hearing the OP's thoughts on that.

Two explanations for variation in human abilities

I couldn't find it quickly, but I think that I read this on codehorror.

Two explanations for variation in human abilities

In an experiment, a group of people who have never programmed before have been showed how to code. In the end, their skills were evaluated in a coding test. The expectation was that they would be roughly normally distributed. However, the outcome was that the students were clustered in two groups (within each of which you see the expected normal distribution). The students belonging to the first struggled while the second group fared relatively well. The researchers figured out the cause: the students that did better managed to create a mental model of what a variable is (a container or a box that can hold values) while those that struggled didn't manage to do this. Are the students from the second group inherently less intelligent?

Yes, because they did not manage to find the right model on their own. No, because once they were provided a straightforward explanation, they were able to code just as well as the students in the better group.
