I've accepted that I'm going to ignore a certain interest for months, maybe years, and then come back to it when my energy for that subject comes back. Of course this means that I have a lot of books and stuff...

In recent years I've gotten better about hitting the library first instead of buying books. It imposes a natural deadline on things: if you couldn't be bothered to start reading in 3 weeks, then maybe it was just a passing fancy.

Getting older helps too. I feel like I have less energy, which needs to be spent more carefully. But there's also perspective that comes with maturity, and the willingness to forgive myself for not being maximally "productive".
