The PARA Method: Simplify, Organize, and Master Your Digital Life

Picked this up at the airport and read it rapidly, made the change to my Google notes, OneNote, work files with positive results, and have tried with email though I've been less successful there. It's proved very useful! Far superior to absolutely no organization :)

It is crisp, sharp and to the point, I could call it a glorified blog post because it is but it's a very good one! Recommended to all that need more organization and those that use multiple tools.
