Hear, hear! You can burn out at anything, even your most beloved hobbies.

I was a video game modder for most of my life, but burnt out on the hobby completely after several years of maintaining a dozen or so mods for an early access game.

Making new features was great, and hunting down reported bugs in my own code was enjoyable. Constantly fixing compatibility issues due to updates (and having to rewrite perfectly valid code due to shifting or deprecated APIs) wasn't.

I love modding, but even things you enjoy get old after a while, and the feeling of obligation to continue (even if only not to disappoint your fans) wears at you.
