Struggling

"A musician must make music, an artist must paint, a poet must write if he is ultimately to be at peace with himself. What one can be, one must be."
- Abraham Maslow

I believe in this quote wholeheartedly, but I have been struggling with it quite a bit lately. I know we're meant to work hard in this life. I know that thousands of people work everyday in a job that means nothing but money to them. Are we supposed to spend the majority of our lives doing something that means nothing to us? How do I do what I love AND pay the bills? How do I find time to do both? What do you think? How do you accomplish this?
