1. Do you have something that gives you the flow effect, when you forget the time and just keep working because it's so interesting? Try to find a professional income based on that activity.
2. If the first thing is too hard - e.g. few novelists can live off their writings -, don't despair. Keep your passion as a hobby, find a stable source of income and have fun.
Assuming that you're still somewhat young, here is one additional advice from someone who has made a mistake in that respect: The older you grow, the more important financial security will become. You may think you're immune to this effect, but you're not. You'll want to have a fairly decent, constant stream of income when you're 40+, no matter what you think about that now.
