Negative confirmation bias being a big one. Do a half-assed job of trying to change someone's mind and they become even more recalcitrant.

I long ago realized I'm not the person who should be leading a group or a club. I respect people who can, and I support them as best I can. It's important work, but it's not for me. Which sucks when the club doesn't exist (I'm currently trying to encourage a couple of people to start one and it's not going well)
