There are lots of things you could do if you have a passion for make up. Have you looked into the different courses available in your area?
I'm not sure where in the world you are, but in London there is even a school dedicated to learning the art of make-up called, unsurprisingly, The London School of Make-Up.
A lot of other cities have similar institutions.
The great thing about some of the courses is that they're short, so you don't have to make a long term commitment whilst you're still figuring out what you want to do.
Another cool idea would be to start a YouTube channel.
Make-up tutorials are huge online, so there should be plenty of people out there who want to watch, but even if there isn't, it could just be a fun thing for you to do for yourself, and a different way to practice you skills. You wouldn't need any fancy equipment, just a camera and a basic editing programme like iMovie.
YouTube has a great community too, so you might find you 'meet' people who have similar interests that you can bounce ideas off.
