One branch of modern philosophy asserts that everyone exists in a set of concentric hamster balls. The wider your world, the bigger the ball is. If you are depressive then your ball is very small. The challenge is to make your ball as big as possible. Eventually your hamster ball is so big you are no longer aware of it and you are free.
Patient: "Man, my world is shit. My hamster ball is so small, I feel so bad. I know some fag is gonna stick me up his sorry ass one day."
