The greatest discoveries often come from unexpected places.

我不喜欢欠下人情，这样会压逼著我，令我觉得自己是个奴隶。我宁愿自己处理自己的事，不用依靠别人，能够完全独立。

好奇心是发现的催化剂。

I got the idea to start Amazon 16 years ago. I came across the fact that Web usage was growing at 2，300 percent per year. I'd never seen or heard of anything that grew that fast， and the idea of building an online bookstore with millions of titles -- something that simply couldn't exist in the physical world -- was very exciting to me. I had just turned 30 years old， and I'd been married for a year. I told my wife MacKenzie that I wanted to quit my job and go do this crazy thing that probably wouldn't work since most startups don't， and I wasn't sure what would happen after that. MacKenzie (also a Princeton grad and sitting here in the second row) told me I should go for it. As a young boy， I'd been a garage inventor. I'd invented an automatic gate closer out of cement-filled tires， a solar cooker that didn't work very well out of an umbrella and tinfoil， baking-pan alarms to entrap my siblings. I'd always wanted to be an inventor， and she wanted me to follow my passion.

To be free is to have no choice.

 我只向上帝祈求过一次，一句非常简短的祈祷：'上帝啊，让我的敌人变得可笑吧。' 上帝实现了这个祈愿。
