[Declanomous]

My grandfather used to do this. He had notebooks filled with what he did every day of his career. It's really cool to be able to go back and look through his notebooks and see what he was doing in April of 1971.

My notetaking is not as rigorous as my Grandfathers, but I do something similar. Every month I make a new manilla folder with the month and year on the tab. Each week I write down every project I'm working on and every meeting I have. If someone brings me a new project I put it on the sheet. Every note I take a meetings and during projects goes in that folder.

At the end of each week I go through the notes from that week and write down anything interesting on that week's note sheet. At the end of the month I go through all the notes and write what I accomplished on the front of each manila folder.

It makes it really easy to keep track of everything you've done, without consciously keeping a journal in the moment. It's also a really easy organizational system. When someone asks, "What did we do for [x] in the past", all I need to do is flip through my folders looking at the front for anything that rings a bell, rather than trying to keep up with a tagged organizational system.

This probably doesn't work if you don't have a file cabinet though.
