I think the biggest innovations of the twenty-first century will be the intersection of biology and technology. A new era is beginning, just like the digital one was when I was his age.

I discovered that the best innovation is sometimes the company, the way you organize a company. The whole notion of how you build a company is fascinating." Steve Jobs

If you act like you can do something, then it will work.

I used to be an angry man myself. I’m a recovering assaholic so I could recognize that in Steve. (quoting Jean-Louis Gassée)

More generally, I made an effort to leave out things that weren't relevant to the main narrative themes of the book, namely that there were two sides to Steve Jobs: the romantic, poetic, countercultural rebel on one side, and the serious businessperson on the other.

The older I get, the more I see how much motivations matter. The Zune was crappy because the people at Microsoft don’t really love music or art the way we do. We won because we personally love music.

Leonardo da Vinci did not take received wisdom - whether from ancient classical thinkers or medieval scholars or from the Bible - without questioning it. And this was the beginning of the scientific method. This is another lesson for our time: that when we have evidence that contradicts a certain belief, we should be willing to change it. I think this made Leonardo, in some ways, a person who better understood the beauty of God's creation than a person who just takes all received wisdom from the Bible on faith.
