I have a notebook called "Captain's Log" that I constantly post things into. I have my Evernote app set to default to that notebook. Everytime I hear something on the radio I want to look up, I type a few of the lyrics into a note and save it and it goes into the Captain's Log for perusal later. Everytime I have something I need to remember to do I post a note into the Captain's log and add a "todo" tag to it so I can sort those out when needed. All meeting notes go in there too. When I start coding something I take notes on what I'm working on in a note so that I can go back and remember what I did when I was working on that thing I can't quite remember.

I can sort that notebook by "date created" and see a log of my life going back in time and I've found it very useful.
