I've spent the last year or two planning the perfect schedule, the perfect study methods, the perfect piano practice plan, and so on, but never got around to actually implementing them. Every time I tried, I worried that I was not doing things in an optimal way and wasting time; obviously I knew I was wasting time even worse by not doing anything, but I was still paralyzed.

This year, I finally decided to just start doing the things I want to do without worrying whether I'm doing things in a horribly inefficient way. I got a piano teacher again so that I would be forced to stick to their plan. I started studying my textbooks and making flashcards in Anki, not worrying about whether the flashcards were very well-crafted or not.

I think the line of reasoning that finally led me out of my rut was that not doing anything was a waste of time, so it would be better to do something suboptimal for a year and only reevaluate my plans afterwards. So even if I'm being inefficient this year, it's better than doing nothing.
