Yes. I do this. In Gdocs though, name is productivity, where I add the day in format [dd/mm/yyyy] followed by bullets points on things I thought and did during the day. It also helps me to wrap my mind around in the following weeks, like, what was I thinking? then I go back to the log, and remember the trail of thought leading to my decisions. It is quite worth a while doing this I reckon.
