Cash flow, bitches
The problem is, being something like that might not even make you enough money to live. You can make music or art whenever you want, it doesn't need to be your job. Sometimes it's more logical to go with the job that allows you to live comfortably.
Unless your passion is sitting in a cubicle.
I just think that work is work, and if you're that kind of person, it doesn't matter if you don't like it. Especially if you get some extra spending money.
