Isn't this dictated by your available free time?

Or project-based? If you are a writer, for example, it's usually project based.

Otherwise, if you really have a hard time setting boundaries, then you might be the type to orient yourself around the states of your social circles. They definitely have boundaries when they stop listening or caring.

If you can't say enough is enough yourself, let someone you trust, or in whose competence you trust, do it for you.

I would say something like "when does it stop being useful" but the 'real' infinite game is all about curiosity and there's almost no players, just uninterested and destructive shareholders, so I'm gonna go with "do you have a thread that connects it all or not?" If you don't, and it only leads to more and more excursions, fix that point of depth where some subject still interfaces with the other stuff and stop there.

Yes, and at its core I’m asking how to use my free time most efficiently
