The arts are a reflection of the real world, which means it has a lot of love, a lot of surprise and a lot of joy.
That also means that it is a world that has sexism, racism, unbalanced power structures and a good number of unfair outcomes.
Trouble arises when we think the arts (and artists/adminstrators) are somehow above the negative aspects of the real world.
Just because someone is an artist doesn't mean they are a good person.
Just because someone works in a nonprofit doesn't mean that they are more generous, or fair, then the guy that works as a corporate lawyer.
If you are going to be a part of the arts world, then dealing with politics, egos, agendas and the like are going to be part of your life. That's not a good or bad thing, that's just how it is.
But I've learned when you can embrace the fullness of the arts world (the good and the bad), life (and success) becomes much easier.
