There's a free report titled, "The 5 Second MBA" by an organization called WhatWouldDadSay. I wanted to take a look, so I filled out the form and downloaded the 49-page report. It's actually a set of slides that include Venn diagrams. After you go through the slides, you'll feel like you've already completed your MBA (almost).
