Evernote, more than any other application, is what keeps me productive, sane, and on-task. It helps me remember everything, helps me get things done, and has all manner of other purposes and uses in my life. My productivity system is based on Evernote as my inbox, my school organization is all based within Evernote, and so on and so forth. I could continue to rant and rave about how great it is, but instead I’ll tell you how it is that I use it. - nik
