I think in general one should try to be nice to everyone but yes, in my own experience, collaboration and being nice all the time is probably not the best strategy. It can be very demanding on one's mental health. I say it because lately I have found myself engaging in far too many emotionally draining conversations with a few friends and coworkers. These are generally negative/depressed/anxious people. Of course, they need someone who they can talk and lighten their loads but they end up passing their load on me. After lunch or dinner with these friends, I feel too tired to contribute anything positive when I am with my other friends or more importantly with my wife. One should not be sounding board for everyone but only close friends and family.
