Obviously I have no idea if this works for you, but for me, it comes down to this:

• The Cycle of Hobbies I jump from one to another without any schedule or plan. Oftentimes I take interest in a new variation of one of my hobbies, but other times I just pick up old projects that (for no apparent reason) are interesting again. But(!) I (by pure chance) have a pool of hobbies that are different enough, which makes switching between them easier.

• enjoy it while it lasts I stopped caring about finishing a video game. I may pick it up in the future (or not) but that does not lessen the enjoyment it’s giving me in this very moment.

• stop it, if it starts to suck I am that I learned to stop reading a book I do not like, to stop watching a series I don’t enjoy or to box a project that becomes to tedious to finish. If it becomes interesting again in a few months or years, I will gladly try it again but if not, it probably wasn’t worth my time anyway.

So long story short:

I burn through hobbies, but I can say with confidence based on experience (and a pinch of hop) that the ones that really got to me will come back eventually.

You can try to write yourself a „dopamine menu“ with stuff you know you generally like. This may at least help bridging the boredom gaps.
