I'm 32 and don't know what I want to do.
Getting ideas and trying as many things as you can will help you get an idea of what interests you the most. Don't let anyone tell you you can't do something because, "it's too competetive" or "doesn't pay enough." If you want it, and you work hard to get it, than anything is possible. If you are happy with what you are doing, the money shouldn't matter. - But do some research, and figure out what's important to You.
I hope you get ideas that will get you closer to your [yet unknown] dream.
