Following a comment I saw on HN a few months ago, I started keeping a daily log for my professional work. It contains what I did that day but also include code snippets and other interesting tidbits I need remembered. It's a simple text file so I can easily search in it. But I use the 'jrnl' python script to help me append to it or view the lasts entries. I found the practice very helpful, it helps me track the previous days or if I had to stop in the middle of a task but also help my work/life balance. I usually set aside the last ten minutes of works to fill it. And if I had to leave in a rush I just send myself a mail from the train so I can append it the next morning. I don't sync it and just leave it on my computer at work.
