The biography of Steve Jobs is incredibly interesting. Know. To be extremely hot headed and brutally honest, his vision created an unbelievable company.
Steve Jobs had a vision to create sustainable companies that produced great products. With Apple and Pixar he did just that. He stated in his book, he was always focused on the product, and boy did that turn out.
I highly recommend picking up the biography written about him by Walter Isaacson. It is long, but worth the read about an inspiring man.
