When I'm practicing, I often find myself spacing out, forgetting what I had just played, or tuned back in to find that, wow, I'm already almost at the end of the piece!
This bothers me because it seems an inefficient use of time, as I'm not actively trying to improve anything. I also end up playing a much larger chunk than I meant to. I also think my problem is preventing me from making that leap from "just an okay musician" to "potentially phenomenal", I guess, if you can stomach the pretentiousness coming from that lol.
Edit: instrument is cello, and my repertoire is currently Bach Suite No 1 and the JC Bach (Casadesus) Concerto in C Minor.
I'm obviously aware of my problem, but merely trying to "be present" isn't helping much. Any speculations, comments, and suggestions are welcome!
