I've gone a long stretch without cubing (think a bit less than a decade) and, while it was refreshing coming back to the hobby, with new hardware and seeing it becoming even more popular, I was forced to confront the fact that I don't have much disposable time to practice.
While this is argument enough, I think, to prioritise focused practice, I generally find that the opposite becomes even more tempting: I generally just do a bunch of mindless solves, and while I do see myself improving, I doubt I'll improve as fast as I could. It's probable, even, that I'm reaching a skill ceiling for mindlessly solving.
I don't know what this is, maybe just a cubing-related rant about getting older.
