I just started logging my practice activities in a journal. My main purpose is to keep my mind dedicated in order to make the best use of my time.
I wonder whether/which categories are important : today I practiced sight reading for 15 minutes and a piece for 30 minutes. I started logging this, but working the piece meant mainly working on polyrythm, so I wonder whether I should count it as "piece" or "technique/rythm".
For those who keep a journal, do you use categories? Which are they? Should the "technique" category used only for "out of context" work? Does it really matter, after all?
