Not being a rock star but showing potential is great. But there are some people who are allegedly always busy, in over their head, etc. And these are the type of people I agree that should be avoided. I've found that more often than not these people are always wasting time in meetings, chatting it up, only to complain about lack of time 1 hour later.

I'm not saying don't socialize and just work ; you just need to balance the two.
