I've always had a pretty long fuse, so I'm not super worried about personality clashes. Im sure they will happen, and I'm sure we'll all make it through them. As a facilitator I recognize that we should be worried more if this doesn't happen.

I typically deal with personality clashes using rule # 5, be relentlessly up beat. It's hard for me to get too upset over something unless it's a personally directed insult, rather than criticism (constructive or otherwise) on my work. When I do get mad, I try to resolve the situation by taking a minute to step back and try to get a look at the whole picture, and after that hopefully the scenario will make more sense.
