This was not about what I'd hoped it would be. Things like: how to realize when you do or do not have sufficient knowledge about something, or how to distinguish bs from non-bs, or how to recognizing when you really need to have situational awareness, or how to maintain proper perspective on things, how to keep calm and when not to, etc.

The skills they mention in the article, budgeting and rejection and so forth, are also important. But there is a layer under that too.
