How to Improve from Where I'm At Now?
 

So I obtained a free kit this past December from a friend, and with some fixing up, it became playable. I can keep time well, and have learned a bunch of basic time keeping beats in 4/4, 3/4, and 7/8. I've learned some decent fills in 4/4 and 3/4.

Any tips on what kind of fills I can attempt in 7/8? And where should I go from here? I'd like to learn techniques for jazz drumming (and more odd time signatures), but I don't know what sort of exercises to do on my own, and can't afford any sort of lessons.

Help is much appreciated!

consult youtube. There are plenty of instructional videos on there.
