You mention things that are not successful in one's personal life. When it comes to your boss, the only success that matters is in terms of the business.
It would be useful to know what industry a/o role these people worked in. Perhaps leadership style is a function of industry? Perhaps personality type draws certain people to certain industries?

The kind you just can't fix.
