I keep a daily log where I scribble down some basics of what I did that day. At the end of the week, I go through that, consolidate it into a few things I did that week, and add it to a git repo. When I need to do performance reviews or something, I read over those summaries. A few bullet points per week is manageable enough that I don't try to condense it further, but I do use them as inputs when I'm doing performance reviews or updating my resume.
