Hobbies with a creation/social component...

Hobbies with a creation/social component are also important to have. Consumptive hobbies are good springboards for it. Media consumption can lead to reflection, discussion, fanart, and community BUT they tend to crumble to fan wank.

It's a good idea to have a more stable hobby to turn to, so that you won't feel like fan wank is the ONLY thing you can go to for leisure. A "touch grass" kind of hobby.

And also creation is just a whole different kind of joy.

The only truly bad kind of hobby to rely on, IMHO, are cash siphons/disguised gambling. Especially when the reward is something you don't actually fully own.
