Seth Godin asks if your anger is killing your art:
It’s rare to find a consistently creative or insightful person who is also an angry person.
They can’t occupy the same space, and if your anger moves in, generosity and creativity often move out. It’s difficult to use revenge or animus to fuel great work.
Most of the blogs I had when I was younger (LiveJournal?!) ended up descending into meaningless rants and complaining sessions. Not fun to read, unrewarding to write. Although, perhaps understandable for high school.
