I use Evernote a lot. I consider myself to be pretty good at using it and getting a lot of value out of it, but that’s only because I have read Evernote Essentials. This ebook, written by Brett Kelly, is a fantastic resource if you would like to get started with Evernote.
I first purchased Evernote Essentials long after becoming an Evernote power user, but Brett’s book taught me a lot of new things. Version 3 came out today, and you should totally go buy it.
