Creative endeavors can be especially difficult because it can mean lots of work with very little chance of financial success. You really have to enjoy the process itself (or at least find a healthy balance between the creation and business sides of it). If you do, there's not much risk, you'll get enjoyment out of it at least. But you really have to be honest with yourself about your expectations. (That is, even if you tell yourself you're doing it for fun, but you're secretly still planning to "make it big", you're probably setting yourself up for disappointment.)
