There's a few broad interests/hopes/dreams that I tend to juggle, as is the case for most people.
I also have this note in my phone called "pipe dreams", in which, whenever I fantasize or think about something that's plausible while simultaneously kinda crazy/life-changing, I write it down. I occasionally visit it when I'm feeling uninspired or bored, and this usually results in me working on something that incrementally reaches towards one of those "pipe dreams".
