I recently listened to this two-part audio interview with Tony Robbins and Tim Ferris, mainly discussing Robbins' new book Money - Master the Game. Supposedly, Robbins breaks down how the average person CAN make a profit on their investments, informing how the markets work, why it's difficult to earn money on mutual funds, and other tips. I haven't purchased the book, so I can't really speak to that. I've read quite a bit about investing over the years, and sort of gave up thinking that I could really 'master' the investment process. And I've certainly wondered how to better invest my money for the long-term. Robbins says that for the most part, it's very difficult to earn a profit on mutual funds. Hmm....
Anyway, you might want to listen to the audio interview, and then see if you want to buy Robbins' book. You can listen at this link [scroll down for the two audio sections]:
