Maybe, but probably not. On one hand, the person would be understanding of your mood swings and probably give you leeway on projects, but on the other hand, you don't know how they are when manic or depressed. You only know you. I'd be afraid of the unknown because some people are VERY socially destructive when manic, or they could start a bunch of new projects and force you to do them all at once. Just a million things could go wrong.

I realize that maybe one of my future bosses (or past bosses?) could have bipolar and I wouldn't know it, but if given the choice, I'd have to pass because I like to minimize risks. No offense.
