Anyway, I also strongly recommend the “Evernote Essentials” book. It’s a light read, and it’s extremely useful—priceless for any Evernote user looking to become more productive and get the most out of the app.
(No, I’m not affiliated with the author in any way, it’s just that good.)

If you’re tech savvy, you may use the Evernote API to use if for just about anything; it’s quite amazing.
