I'm like you. I call that "being passionated in passions" ^^ (rough french translation).

What I would recommend is to truly question what is the deep root of the interest ("where does it comes from") : Is it in reaction (for example, is it to escape something ? Is it because it's easier to have an other interest than to push when it becomes a bit harder? ...) ? What has captured your interest precisely at this moment ? If you answer all these kind of questions, I think things will begin to sort out already naturally.

If I go deeper in the answer, as we all are mostly in "productivity-oriented life" (or at least utilitarist-oriented life), our environment (friends, life, ...) tend to push us to do things which "has to" be "useful". Useful for our advancement in career, useful for an instantaneous joy, ... But when we reason like that, we tend to forget that not everything has to be useful. It's good to be passionated. To have many interests. Even not useful.

Just be gentle with yourself. In the end, it's not a race to the bottom. It's YOUR life, not the others, and it's yours to choose what you want to do with it.
