Form Austin Kleons book Still like an artist
Just as you need a chart of future events, you also need a chart of past events. A logbook isn’t necessarily a diary or a journal, it’s just a little book in which you list the things you do every day. What project you worked on, where you went to lunch, what movie you saw. It’s much easier than keeping a detailed diary, and you’d be amazed at how helpful having a daily record like this can be, especially over several years. The small details will help you remember the big details.
