What You Believe Affects What You Achieve
I have the book, started reading it about a year ago and stopped halfway, because my bullshit cup got full.The reason I think this book is nicely packaged bullshit is because it presents exceptions as rules and then tries to build a theory out of it.I wish it were as easy as Dr. Dweck describes it, but there are gotchas.I can agree with the distinction of 'fixed' versus 'growth' mindsets (although... .. how do you measure that?), but that success is guaranteed if you believe and try... Not necessarily. 
Ask 9 startup founders out of 10.Not achieving "success" (failing) is rarely free: it leaves emotional and physical scars.. 
Repeat it a couple of times and you're either dead or on your way there.No, success is not guaranteed even if you try many many times times, even if you train a lot and believe a lot.In fact, the rule is this: No matter how hard you try, you might still lose. 
Sorry about that.And the reason for this is not mindset - the reason is your definition of success. 
If you try to win at the wrong game, you will probably lose at it. So pick your game wisely.Of course, a fixed mindset will only land you some semi-boring job, a family, a couple of kids and a lot of mainstream entertainment.. I guess that's the definition of "failure" these days... But is it ?*By the way, if you want useful advice about how to be successful in life, Bill Gates is a very bad choice. It might be counterintuitive at first, but think about it ... 
As a bird, is it smart to fly around with your mouth wide open in order to catch food... because that's what the whale does ?
