6-7 years ago, I started learning how to drum. However, I was a kid, and whenever I played or even had a lesson, it basically just ended in my trying to learn to play whatever rhythms of whatever songs I liked.
As a result, I can pick up some rhythm from some drum tab decently well, however my general drumming ability is, well, close to nonexistent. I don't have any knowledge of music theory, have a hard time "getting" the beat from listening to a song, have a hard time staying on time or playing over a song, and just don't know any of the stuff I should know.
Basically, I feel like a total beginner even though I technically shouldn't be.
Therefore my question: Do you guys have any advice for me on how to get better? What exactly should I train/learn first, and prioritize? How?
