I'm making a new watercolor version of this for my Institute of Sound students- (you can download one too, at my link above!) It's one of the tools I created for teaching and quickly realized it was something I had been needing all along for myself. How easily can I think the playing isn't progressing, but my log shows the facts: How I spent my week, where to keep carving instead of traipsing around. Whether or not I actually spaced out completely (like the week of Oct 9!) My hero Austin Kleon (of Steal Like an Artist) calls them logbooks, like we're on a ship logging its progress over what seems like an undifferentiated sea of process. This summer I started a digital version of this that's shared with one of my teachers, Moorea Dickason - a fantastic way to turn up the heat a bit on following through on my goal of playing 2 hours a day, 5 days a week.
