The Bipolar Scale of Artistic Angst

 This is the best idea I've ever had, I am unstoppable. There is no limit to what I can accomplish. Get out of my way, I have important things to do. I'm feeling fortunate for my situation. Things could be better. Things aren't that bad. I have no reason to complain. Life is really hard sometimes. Nothing I do is any good. Everyone else is better than me. There is no hope for my future.

Repeat.
