Thank you for a great post. I, too, struggled with the notebook vs. tags decision. When I first started with Evernote, I went the notebook route, but quickly discovered that it became so unwieldy that I soon stopped using Evernote altogether. Like Iosephus, I came across “The Secret Weapon” and using that format of tags over notebooks, Evernote has not become one of the most valuable and indispensable tools I have in my GTD arsenal. Now, I only use a few notebooks. Even though the idea of over 100 tags may seem daunting, I have found it far easier to sort and classify notes with tags rather than notebooks. For those still struggling to discover a system that works for them, I would highly recommend checking out “The Secret Weapon.” It literally changed my life and the way I use Evernote.
