I once had a computer science teacher (Patrick Winston for those who keep track) who said “the purpose of the first date is that the second date isn’t the first date”. I went on to major in math.
Such is the way with practice. Don’t worry about the point of practice. Just be glad the next one will somehow be better because of what we struggled through today.
Therefore to honor practice, I need not internally berate myself on the quality of my practice. The only thing I should take out of practice is notes about what worked (C3 is sounding better and D4-C4-B4-A4-G sequence sounded good, and the crispness of some fingering changes) and what didn’t (bow speed and weight on the D string).
I’ll continue to look up for now.
