Not everyone is interested in becoming a billionarre (as hard to believe as that may sound). Money is not a good motivating factor for genius, and I'm not just saying this moralistically. Genius involves a fundamental advancement of human knowledge, or spiritual experience if one is so inclined. Making money is not such a rewarding task as discovering new things about the amazing world we live in, in my opinion. Furthermore, I am skeptical that any of these techniques, as such, are capable of creating a true genius. You do have a point, however. People can use their increased mind-power to earn career-advancements and possibly to formulate schemes for getting rich. None of these techniques are guaranteed to help one do that so easily. It would still require an enormous investment of time and effort. Personally, I'm not willing to do that, although I would have been a few years ago. I'll use these techniques to better myself and better my understanding. Becoming rich is a secondary benefit; I won't sweat it.
