Not quite 2 years ago (around march 2015) I read an article on lifehacker about keeping a list of your accomplishments. I can't find the original article any more, but here's one from this year. The premise is simple enough. Once a week sit down and focus on what you actually managed to get done. Around the same time my wife had a conference in New Orleans and I picked up a nice leather bound journal that I've been using ever since. Sometimes I'm a day or two late.
