I watched the first 2 min and like 15 min from 16:00 on. it's okay I guess but he just mixes a ton of topics.
philosophy: complete bullshit. he is just a religious guy and doesn't actually explain anything. "work hard and be successful", okay, then what? why? religious people simply justify this with god, like if you worked hard and were a good Christian so you get to go to heaven but nobody knows whether this is actually true. he also implies a ton of very questionable things like free will, that we have the power to decide our faith...
psychology: it's basically just a pep-talk. nothing wrong with positive thinking and setting yourself goals but the guy really overstates the effects of that. Of course you will be more successful of you get up every day and work 12 hours. But many people can't do that or don't see the point in it. So it's just selection bias, of course successful people will tell you that you simply have to work hard but just because it worked for them doesn't mean it works for everyone.
Economics: doesn't really support his claims. you can look at stuff like social mobility. many people fail simply because they are at a disadvantage and there are things you can never really catch up with or at least it's very hard. e.g. go tell some 12 hours/6 days per week Chinese factory worker that positive thinking and hard work will make them rich.
Anyway, I don't think it's bad it's just that those type of speeches are pretty unscientific and don't do much for me. Or maybe I am just too much of a cynic.
