The first camp is those who believe that you should find a job in a field you love (maybe that's art). The idea is that even if you don't make much, you'll be happy and have the drive to do well.
The second camp is that you should find a field you don't necessarily love, but is more stable/higher paying and thus allows you to comfortably do the things you like in your spare time.
I've heard these two argued to death among students in high school and among parents today. I took the second route and am happy with my choice, though I agree it's not for everyone (really depends on the work you do and whether or not you have the time/energy/will to work on your creative passions).
