commission work

i don't know how to feel about doing commission work. as an artist, i want to do the art that comes out of my own mind but yet i have to make money to be able to make this art. i like being able to make people happy by doing art that they enjoy but does it truly fill my artistic yearning? i think as long as i don't become an artist that solely does commission work i will be okay but it still seems unsettling. but i suppose in this economy i should suck it up until i can afford to paint what i want to.
