Write them down somewhere you know you’ll come back to them. This lets your brain let go and stop chewing on them.

Review what you’ve written down fairly frequently (weekly or so). You won’t have enough capacity to act on all or even most of it. Extract the most important items.

Put the rest in a “someday/maybe” list that you review rarely (quarterly or annually) to keep your brain satisfied that they’re not lost permanently. When reviewing this list you can remove anything that no longer interests you.
