Right now I feel as if I have too many interests and don't know which one to pursue. I like them all about equally, what should I do? Right now, I am dabbling in all of them, but I want to become better in at least one. I want to make sure I do something that will help me support at the very least myself, but I want to still have fun.

Depending on your current age of this post it may differ what actions you may want to take. Feeling as this may affect your future life and how you live I would simply suggest the activity/interest you're currently comfortable in and enjoy doing, however it may be something that has no involvement in the current job market; with that said I would suggest talking with a parent or adult you trust on the matter.
We live in a wonderful time.

Just as >>2 said. It would depend on your age, as you grow older your choices will get narrower. Just deal with the things you like in a minor level and prioritize the things that would provide you a living.

Thank you
