The author is a productivity guru/expert. This is his first book that essentially walks you through why it's important to keep electronic notes, as well as how to organize electronic notes to essentially become your second brain.

He recommends proceses to review and plan that should help an open reader to align and improve their day/week.

The concepts are rather simple and easy to grasp. I don't doubt that his premise of information overlode isn't incorrect. I read this as I wanted to organize my notes better, and it really helped me think and plot that out.
