True fans can't ruin shows.
I tweet too much. I can't even pretend it's because I'm talking to fans.
I collaborate with people who know I'm a control freak.
Listen to people. Listen to yourself at the end of the day, but listen to people a lot.
You can't do all the work, so surround yourself with people you trust; if this is your show then everything is ultimately your call, but the more faith you have in people who have proven to be capable, the more sane you get to be.
No one can ruin shows, but Internet trolls sure can make things miserable.
