Be happy, but never satisfied.
生活要快乐,但绝不要安于现状。
The only limits in life are the ones you set for yourself.
We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes.
最奇妙的事情莫过于生活在一个充满奇迹的世界里。
La ciudad no es solo un escenario, es un personaje más en la novela.
