I think the reason why I am who I am today is because I went through those tough times when I was younger.

You are never too old to set another goal or to dream a new dream.

The true genius shudders at incompleteness — and usually prefers silence to saying something which is not everything it ought to be.

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！"

所有这些说明的目的是引导探索者的心智朝向它们背后的唯一实相。

只要生者还在记忆，逝者就从未真正离去。
