我们不是从祖先那里继承了地球，而是从子孙那里借来的。

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!

Don't be afraid to give up the good to go for the great.

如果你简单，这个世界就对你简单。
