I see it a bit differently. Some people get on a cycle of taking action, reviewing the results, and learning to improve the results of their next action. All three of those I cited have that in their DNA (or so it seems to me). Learning from others is a key aspect of that approach. In reviewing the results, and even before taking the action, search for how others have approached the same problem. Not necessarily to copy them, but to identify what worked and adopt it, what didn't work and avoid it, then, synthesize and move forward to the next challenge.
A Musk quote that stuck with me came in the midst of one of his Twitter escapades wherein he was regularly attacked for seemingly erratic, likely sleep-deprived statements. He came across as very defensive to a reporter who asked him if he felt he could accept criticism. He responded, "How do you think rockets get into space?" He may not be so concerned about how Wall Street perceives his character, but when it comes to SpaceX, and likely all of his serious endeavors, he's relentlessly critical of solutions.
Hacker News is just one source to get ideas, learn new things and practice rational thinking. Folks around here are more than happy to help hone your skills. If you can carry that into daily life, you'll catch a rabbit or two.
