Last month I made myself a practice log/chart.
Basically a Word table with the days of the week across the top, and lines for each of the areas I wanted as focus for my limited practice time (like Reading, Doublestops, Jazz Gym, etc.)
I've found it really helpful (though I could be better about filling it out - some days I forget).
It lets me track whether I'm working on what I *want* to be working on, and to see if I'm tending to skip certain areas (so that I can either refocus my practice and get to them, or re-evaluate whether this is the right time to work on them).
When I write it down like that, it sounds a bit compulsive
But it is definitely a major help to me, focus- and practice- wise.
Anyone else doing this?
