For me as well. There's usually something I zone in on, sometimes to the point of obsession. It's different than OCD....it's more like I get overzealous about something in particular, and it often turns delusional.

I also get impatient and quick to "snap," especially when others do not agree with my plans when they get grandiose. I'm starting to notice little signs of getting hypo.....feeling especially elevated, so many ideas, etc., but I haven't lost my judgment completely. That is a big sign of mania coming for me....I get unreasonable and take a lot of risks that result in consequences.
