Time travel is the most frustrating thing in the world. You can't change anything, and you can't stop anything from happening.
变化是不可避免的,但进步是一种选择。
Twenty years from now, you will be more disappointed by the things you didn’t do than the ones you did.So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover. (注:这句说话被部分人质疑不是由马克·吐温所说的。)
The biggest risk is not taking any risk. In a world that is changing quickly, the only strategy that is guaranteed to fail is not taking risks.
