Art is God's gift to mankind.

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！"

Gratitude will unlock all other virtues and is something you can get better at

Every day is a blessing, even the bad ones.

"We are all born mad. Some remain so."

在金融领域，唯一可以确定的是没有确定性。

Suffering! We owe to it all that is good in us, all that gives value to life; we owe to it pity, we owe to it courage, we owe to it all the virtues.
