What I'm really lousy at is anything that requires a lot of patience to do well. I'm done in before I begin.
I have very lousy spatial visualization so I get lost sometimes in familiar places. I would not be a good navigator or pilot. No sense of direction at all.
I would not be a good counselor for drug addicts or drunks. People do that to themselves and so I can't be sympathetic to their plight. Being a counselor REQUIRES being sympathetic doesn't it?
I don't like to "manage" people. I like to work as a team member or on my own alone. But when you "manage" people you have to put up with their petty little personality clashes and/or "office" politics and I just don't like wasting time on stuff like that. Not good at it.
So what about you? Where do your strengths lie and what do you avoid for lack of talent at or interest in it?
