There is more than one kind of freedom... Freedom to and freedom from. In the days of anarchy, it was freedom to. Now you are being given freedom from. Don't underrate it.
自由不止一种……自由去做和自由免于。在无政府状态的日子里，是自由去做。现在你被给予了自由免于。不要低估它。
与其不受教育，不知不生，因为无知是不幸的根源。
我愿你快乐，即使你的快乐不再是因为我。
坚持梦想，永不放弃，总有一天会成功。
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！"
I don’t care about the haters. I just keep moving forward.
