It is the preoccupation with possessions， more than anything else， that prevents us from living freely and nobly.

Technology should be invisible. When it's working best, you don't even notice it.

应对不自由世界的唯一方法是变得如此绝对自由，以至于你的存在本身就是一种反叛。

Chaos isn't a pit. Chaos is a ladder. 

质量不是一次行为，而是我们必须每天培养的习惯。

Security is sleeping in the back seat of the car...When you're a little kid, and you've ben somewhere with your Mom and Dad, and it's night, and you're riding home in the car, you can sleep in the back seat...You don't have to worry about anything...Your Mom and Dad are in the front seat, and they do all the worrying...But it doesn't last! Suddenly, you're grown up, and it can never be that way again!

可持续性不是一种趋势，而是我们对后代的责任。
