That's been me every day. So many things I want to do, so little time! And then get stuck deciding. What helped me was making a list of things I'm interested in, prioritize that list and cut the things I can live without for now. Then I rotated those things on a weekly basis. When I stick to one thing for too long, it starts to feel like a chore, so I go back and forth to switch it up.
