I keep todo lists of various sorts. But recently, I added what it effectively a done list. I bought a spiral-bound monthly planner and a pack of colored felt-tip pens. At the bottom of each month's page, I create a legend for the different categories of tasks (e.g. different projects, personal goals), and each time I complete a Pomodoro (25 minute block) in a category, I fill in a corresponding circle for that day. I also summarize the achievements of the day in writing. It's surprisingly motivating to look down and see all the progress that's been made.
