Currently, I track progress in an Excel sheet with a row covering details of each meeting. Separately I have a weekly log to track the trajectory of and thoughts on each project.
I'm looking for a system that is both simple and efficient.
The biggest help has been having custom constructs such as "```timekeeping" blocks to contain time logs, and also having a "clean-out" ritual where I archive things once in a while.
