Every seed we plant today is a promise to future generations.

The more you know, the less you need.

At that age， I'd take any excuse to make estimates and do minor arithmetic. I'd calculate our gas mileage -- figure out useless statistics on things like grocery spending. I'd been hearing an ad campaign about smoking. I can't remember the details， but basically the ad said， every puff of a cigarette takes some number of minutes off of your life: I think it might have been two minutes per puff. At any rate， I decided to do the math for my grandmother. I estimated the number of cigarettes per days， estimated the number of puffs per cigarette and so on. When I was satisfied that I'd come up with a reasonable number， I poked my head into the front of the car， tapped my grandmother on the shoulder， and proudly proclaimed， "At two minutes per puff， you've taken nine years off your life！"

We must remain curious and never stop questioning the world around us.

生活不是如何在风暴中生存，而是如何在雨中起舞。

我试图理解这个地方，它的记忆，它的光线，它的材料，然后我试图找到正确的答案。

Average returns sustained over an above-average period of time yield extraordinary results. Buy and hold.

真相是一面镜子，反映出我们真正的样子。
