> For me it is beyond trying to make money or become famous,

To clarify, when I speak of "approval", I'm not imagining a successful career or financial success. It's much more basic, i.e. having a few people tell me they genuinely like something I created would do that.

> it is simply to enjoy the journey and the creativity that comes with creating music.

It's unfortunately not simple for me (again, context of long term burnout / depression etc). If I only go by enjoyment, I will watch TV and maybe read and go on bike rides until the end of my days. But that is not fulfilling in the long term. I have a creative drive, but it's rather intermittent and not enough to consistently want to do the work involved. I'm trying to nurture it.

If you're after that, try performing for (campfire guitar? Christmas carols?) or with (entry level jams, especially electronic ones) other people. Much easier to start out that one would think, but it requires a lot of self-confidence. With performing, you can scratch that creative itch by adapting/embellishing source material. A small lick here and there or a handful of alternative voicings are enough!

Uh, have you tried rhythm games?

You can scratch the same music-exploration itch with a much lower time commitment and get the same thrill of accomplishment as you improve. There is also a built-in crowd of other players at any skill level that you can share your achievements with.

It's not the same glassy-eyed state as you'd get with normal video games, TV, or doom scrolling at all. You will need to focus and clear the mind.
