I did a Google search and it does seem that it was originally from Tim Ferriss "4 hour work week", but I did see a site called lowinformationdiet.com that has a seminar that you pay money to do. It actually did look kind of interesting, but of course I'm not going to pay for it.
Thanks for posting this. Now I have something else to read about! I probably need this because I think I suffer from information overload. I read a lot about a lot of things, but they never seem to sink in.
