I've been reading this for over a month and I'm still only half-way through a book of only 260 pages.
EDIT: Finally finished it, terrific book.
Josh is the kid from "Searching for Bobby Fischer", a chess genius and 8-time national champion who has gone on to become a Tai Chi Push-Hands World Champion and now a brown belt in Brazilian Jiu-Jitsu training under Marcelo Garcia.
His insights into the learning process, at least for myself, are great. I have pages and pages of notes, that I see parallels in my various pursuits (I'm a hyper-competitive video game player, surfer and Jiu-Jitsu student). Due to his book I've also started playing chess and really enjoying it -- I hated it as a kid, but I'm enjoying trying to make sense of the game.
I don't know if someone who isn't competitive would derive much from this book, but I'm very thankful it was written -- a guide to the mindset and attitude necessary to win and improve.
