We're in an era in which we want to believe people have roughly equal potential. IQ gives the lie to that.

Some people who are recovering from depression want to use the lessons they're learned in coping with depression and their empathy for people with depression. Others want their career to have nothing to do with depression.

I believe that a core problem with undergraduate education, especially at research universities like Harvard, Stanford, NYU, etc, is that most teaching is done by PhDs, who by temperament, training, interests, and rewards are researchers first. So they spend most of their time and energy probing a snip of a field's cutting edge. In my view, the attributes needed to be a transformative undergraduate instructor are pretty orthogonal to that. It would seem that undergraduate education would be superior if there was a separate track for teaching faculty.

Only someone who already knows and likes you is likely to give you a good job with modest relevant experience.

You might want to keep trying to rise, using a path that builds on your natural strengths: sales, analysis, managing people, whatever, and keep asking for honest feedback. When you reach the point at which it feels clear you've topped out, revise your job description or take a step back. Up is not the only way.

What may create even more jobs is to develop more entrepreneurs, of course, ethical ones.
