This short book brings together half a dozen of Guy's articles on productivity, time management, and generally getting shit done. It is short (about 12,000 words) because if you are pressed for time, do you really want a great big doorstop of a book to get through before getting on with your life?
NOTE: you can read all of these articles for free on his blog. But do you have the time to sift through all of the sword-fighting and other stuff on there to find these?
Guy gets a lot of shit done, from founding a martial arts school, to writing and publishing books, producing a card game, writing 300+ blog posts, and so on. This is his take on how to do it.
