I’m 47 and I’m not sure if I’ve had a midlife crisis, which probably means I have not. My adult kids, however, joke that I’ve had one a year for as long as they’ve been alive. I’m what the late Barbara Sher called a Scanner. I keep a Scanners Daybook and lots of other notebooks and I’m always working on a new project or hobby. When someone asks about my hobbies I often say that I’m a serial hobbyist.
I’ve never heard of a scanner or a daybook. Coincidentally, I’ve been deeply invested in finding the best way to keep notes… But a non-digital format loses a lot of utility without searching, etc… Maybe I should try it anyway.
