I've had the same opinion of him as a snake-oil salesman. Most of his stuff is over-exaggerated. For Chess he says start at the end game and master that first like that's all there is to it. Whereas most people would recommend a multitude of things like do puzzles, read a good book and actually play a lot more classical games etc. Your biggest problem starting out is actually controlling your blunders. For swimming he recommends total immersion swimming, which if found slightly better, but you have to actually do a lot more research and find out a lot more by yourself and also there's differences between salt-water(sea) and freshwater(lakes/rivers). But i still found Terry Laughlin technique to be a good way to start and have some concrete goals to practice, but without a coach i still feel stuck and haven't got my breathing technique down for long swims. For language he gives you like 6 sentences to learn about grammar to get familiar with sentence framing and frequency lists and that's that. What i did find him good for was finding people, books and experts to use as a starting point for my own research. I did find Tools of Titan more interesting, but i still think it qualifies as productivity porn. I barely remember one single thing that i've imbibed into my daily life that i already didn't come across from trial and error.
