I'm skeptical that the novel will be "re­invented." If you start thinking about a medical textbook or something, then, yes, I think that's ripe for reinvention. You can imagine animations of a beating heart. But I think the novel will thrive in its current form. That doesn't mean that there won't be new narrative inventions as well. But I don't think they'll displace the novel.

We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that, because we believe -- and we have to take this as an article of faith -- that by keeping our prices very, very low, we earn trust with customers over time, and that that actually does maximize free cash flow over the long term.

What I want to talk to you about today is the difference between gifts and choices. Cleverness is a gift, kindness is a choice. Gifts are easy - they’re given after all. Choices can be hard. You can seduce yourself with your gifts if you’re not careful, and if you do, it’ll probably be to the detriment of your choices.

When you receive criticism from well-meaning people, it pays to ask, ‘Are they right?’ And if they are, you need to adapt what they’re doing. If they’re not right, if you really have conviction that they’re not right, you need to have that long-term willingness to be misunderstood. It’s a key part of invention.

Things never go smoothly.

We like to pioneer, we like to explore, we like to go down dark alleys and see what's on the other side.

Seek instant gratification - or the elusive promise of it - and chances are you'll find a crowd there ahead of you.
