I've kept a journal of some sort for the past 10 years. Sometimes they're mostly used for capturing work tasks and working out architectures and designs, but occasionally I'll brain dump a random essay/poem/song/business ideas there, and those can be fun to come back to. I just moved into a new place unpacked them, so I've been paying through them as I get a chance. It's fun to see all the ways that I've changed, but it's actually more interesting to see some of the ways I haven't changed at all. I enjoy the act of writing because it makes me feel like my sense of self is less ethereal. Having something concrete that I made and like, even if it's just for me, is just satisfying.
