Interesting subject. I think the most interesting thing about him is that he kind of distanced himself from society for a good 10 years to build his company. Kind of shows what it takes to make it, you gotta dedicate your life and be willing to have those dark days where you're off the radar.
If you want to learn about success in business styles, I recommend learning from Sam Walton aka founder of Walmart. He has a book called 'Made in America', it's a great story about business and entrepreneurship. :)
