世界是一本书，不旅行的人只读了一页。

History is that certainty produced at the point where the imperfections of memory meet the inadequacies of documentation.

羞耻的基础不是我们的个人错误，而是我们必须成为别人希望我们成为的那种人的耻辱和屈辱。

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！"

To die is nothing, but to live defeated and without glory is to die every day.

I’m not a guy that’s going to let my family down.
