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)

Leonardo da Vinci had such a playful curiosity. If you read his notebooks, you'll see he's curious about what the tongue of a woodpecker looks like, but also why the sky is blue, or how an emotion forms on somebody's lips. He understood the beauty of everything. I've admired Leonardo my whole life, both as a kid who loved engineering - he was one of the coolest engineers in history - and then as a college student, when I travelled to see his notebooks and paintings.

On the day he unveiled the Macintosh, a reporter from Popular Science asked Jobs what type of market research he had done. Jobs responded by scoffing, "Did Alexander Graham Bell do any market research before he invented the telephone?

I think different religions are different doors to the same house. Sometimes I think the house exists, and sometimes I don’t. It’s the great mystery. (Steve Jobs)

Jobs has within him sort of this conflict, but he doesn't quite see it as a conflict between being hippie-ish and anti-materialistic but wanting to sell things like Wozniak's board. Wanting to create a business.

A popular feel for scientific endeavors should, if possible, be restored given the needs of the twenty-first century. This does not mean that every literature major should take a watered-down physics course or that a corporate lawyer should stay abreast of quantum mechanics. Rather, it means that an appreciation for the methods of science is a useful asset for a responsible citizenry. What science teaches us, very significantly, is the correlation between factual evidence and general theories, something well illustrated in Einstein's life.

I think Leonardo da Vinci teaches us the value of both being focused on things that fascinate us but also, at times, being distracted and deciding to pursue some shiny new idea that you happen to stumble upon. Balancing intense focus with being interested in a whole lot of different things is something that we have to do in the Internet age.
