One thing I once saw a coworker do but I never managed to do for me was he'd write down what he'd just done, every 30 minutes or so over the day. He told me he does that so whenever someone would come and ask him how he had spent his time at work he could just read out his records. I think that's smart. These days almost everything I do I do under git version control. I wrote a script that goes through all the dozens upon dozens of project directories and collects all the commit histories, so I can run that and get a chronological view of all the things I've done over the past days and weeks. I can say that I often do it just to see it for myself and I often find some things in those logs I could not have told you from memory. This is just one teensy piece to get along with a problematic manager but might help if you walk into those meetings withs reams of printouts, ideally after having marked off the more important stuff.
