All failed companies are the same: they failed to escape competition.

I think markets are often not thinking on a long-time horizon, I think that our government structurally is doing even less so. When we have a government where we have people who are up for election at most once every six years for a U.S. senator, that's a time horizon that is much shorter than in a market that a company is looking at 10, 15, 20 years which is a time horizon over which a stock price is typically valued.

Consider the trivial but revealing hallmarks of urban hipsterdom: faux vintage photography, the handlebar mustache, and vinyl record players all hark back to an earlier time when people were still optimistic about the future. If everything worth doing has already been done, you may as well feign an allergy to achievement and become a barista.

For a new payment product, you always have to ask, how much better is it than the current solution? So when we started Paypal, for eBay micro merchants, it was much better than getting the 7 to 10 days process of cashing a check in the mail. When you look at stores or physical worlds, places, a lot of these places are already set up to take cash or credit card. Apple Pay may be an incremental improvement, maybe a little bit better. But when you have something that's pretty good and you go to something that's perfect, sometimes it's very hard to drive adoption because the delta is not that big.

Had the people who started Facebook decided to stay at Harvard, they would not have been able to build the company, and by the time they graduated in 2006, that window probably would have come and gone.

Moving first is a tactic, not a goal.

Brilliant thinking is rare, but courage is in even shorter supply than genius.
