All Rhodes Scholars had a great future in their past.

Every university…seem[s] to reassure you that ‘it doesn’t matter what you do, as long as you do it well.’ That is completely false. It does matter what you do. You should focus relentlessly at something you’re good at doing, but before that you must think hard about whether it will be valuable in the future.

There is perhaps no specific time that is necessarily right to start your company or start your life. But some times and some moments seem more auspicious than others. Now is such a moment. If we don’t take charge and usher in the future - if you don’t take charge of your life - there is the sense that no one else will.

Everybody has a product to sell—no matter whether you’re an employee, a founder, or an investor. It’s true even if your company consists of just you and your computer. Look around. If you don’t see any salespeople, you’re the salesperson.

Customers won’t care about any particular technology unless it solves a particular problem in a superior way. And if you can’t monopolize a unique solution for a small market, you’ll be stuck with vicious competition.

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.

All happy companies are different: each one earns a monopoly by solving a unique problem. All failed companies are the same: they failed to escape competition.
