1) It takes 10,000 hours of practice for us to become insanely good at anything. Once we are insanely good, we have a good chance of making it really big. HINT: Bill Gates had 10,000 hours of programming by the time he was 21, Ronaldo with football.. among many many other examples.
2) Not being able to make a billion bucks may not be our fault. A lot factors need to fall in place for us to succeed and this is really where the book is a masterpiece, at dissecting the truth behind success stories that normally have ‘rags to riches’ and ‘hard work’ written all over them.
Having said that, not being able to make a million bucks definitely means we haven’t spent 10,000 hours on our 1 skill which could make us world class. Dabblers only good for cocktail parties as Jack Welch puts it.. :)
3) We don’t have to be the best. We just have to be good enough. There is a threshold level for everything.. for eg: in terms of IQ, the threshold level is 120. Anyone above 120 is equally likely of making a nobel prize. Just like a person with an IQ above 120 at columbia university has an equal probability of winning a Nobel Prize versus a person in Harvard. Basically, IQ becomes redundant when faced with a bunch of smart people above the threshold..
