I wouldn't say mine rotate, since that implies an order, but they definitely have periods of greater or lesser focus relative to my other interests. (Except for my interest in relationships, that's always high.) Right now, writing and math are high, while chess puzzles and science journals are low. I still enjoy the latter two, but they're in the backseat for the time being. That can change rapidly, though.

I relate to this so hard! Uncomfortable is exactly the word for it. I've got no idea what to do with myself during the rare periods where I'm not interested in anything. It's not a depressed state, but it's still like all the color's been sucked out of the world. I'll force myself to do stuff in hopes something sparks, but it rarely does. Usually I just have to wait out the low period.

Curious about almost everything. I'm especially interested in chess puzzles (warning: I'm not good at them), writing fiction, and reading scientific journals, particularly articles that I can use to improve myself or my life somehow. PMs welcome.
