Every Tim Ferris thread I see on HN, has nigh 10 - 20 posts that all essentially say: "Tim Ferris is a charlatan. He's relies on spin and marketing to sell his products. His methods encourage people to be lazy and not make a genuine effort to reach their goals. His advice is counterproductive." But while Tim makes every effort to support his claims using facts, anecdotes and citations these sorts of comments are rare…
Exactly. And when he's talking about winning the martial arts fights, he goal was to "WIN", not to play the game. And like gursikh says, either put up or shut up. We need concrete examples! Overall, I think Tim has done a lot for a lot of people with the ideas that he shares in his books.
He didn't prove his ability to fight was superior. He didn't prove his mastery of martial arts was superior. He proved his ability to push his opponent over the line.
If there were no line, he'd be crushed.
