He had the attitude that he could do anything, and therefore so can you. He put his life in my hands. So that made me do something I didn't think I could do.... If you trust him, you can do things. If he's decided that something should happen, then he's just going to make it happen. (Elizabeth Holmes)

Was he smart? No, not exceptionally. Instead, he was a genius.

Leonardo da Vinci was comfortable being illegitimate, gay, a misfit, a heretic. But he also respected other people. He didn't get into disputations. He was a genius but he had a certain humility. In his notebooks you see lists of people he wanted to grill about things like how the water diversions in Milan work; he was always interested in learning from other people.

When you write biographies, whether it's about Ben Franklin or Einstein, you discover something amazing: They are human.

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.

If you truly have a passion for what you do, you will care even about the parts unseen.
