I played drums like a crazy person in high school. It was like once I got started I could just keep learning and doing different stuff with no limits.

Strangely enough I think the biggest thing that affected me in learning the coordination part was learning how to read a beat, almost like reading music. Once you understand the basics of the technical side the creative side should just flow. Of course you do have to have a level of hand/eye coordination too. And practice more than just off and on. It takes a lot of stool time to get good.
