Ask HN: What huge mistake did you make early in your career?
My biggest mistake, that I made again and again, was not leaving a job when it was time. I thought I had something to prove, but there was never any point to it. You don't owe anything to an employer. You can't prove anything to an employer. They have absolutely no loyalty to you, and care less than nothing about what is right or wrong, wise or foolish.So: If you ever think things might not turn out as well as you hoped, move on. There is so much else going on in the world that is at least as interesting as what you are doing, where you have a much better chance of making a difference, that spending time on things that you might not end up proud of is a terrible waste of your short time on Earth.
