I'm ten years in as a drum student. I've thought long and hard on this subject. I've written extensively on this journey. More here: The aging musician.
In the meantime enjoy the following videos.
Video one suggest classic ideas around staying motivated.
The second video is done in the style of classic motivation videos that litter the internet, complete with a ridiculous up lifting soundtrack. (Any moment I expect Tony Robbins to bounce into frame.) It's fun, you'll laugh, and it will help you to stop reading this and get back to the piano bench.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
I'm a professional pianist and music educator in West Toronto Ontario. I'm also a devoted student and teacher of the drums.
