Although it may not be apparent from how I carry on here, I spend most of the time thinking about pragmatic solutions to concrete problems. Maybe that's not a surprise—I do spend almost 100% of my time thinking about problems and how to solve them, I just file the abstract ones online.
Not everything is a problem, of course. Maybe nothing is? (The problem of problems.) My personal theory of Acceptance tells me this. Acceptance, of course, is the ever-retreating goal on the horizon, never quite where I find myself in the moment.
