Although this isn't specifically code golf, I think code golfing as a hobby can be fun and a good learning experience. It's fun to take a working block of code and try to trim it down as much as you can, often learning about lesser known built-in functions and syntaxes as you go. Seeing your weird slurry of bytes come to life upon execution to fulfill some task is rewarding.
