The only limits you have are the ones you set for yourself.

成功不是一种权利，必须通过努力获得。

In looking for someone to hire, you look for three qualities: integrity, intelligence, and energy. But the most important is integrity because if they don't have that, the other two qualities, intelligence and energy, are going to kill you.

译文：感叹白发，观察世间的道路。人们无不追求荣华，看重富贵而轻视贫贱。显赫的宫门，华丽的宫殿。年轻时入仕，幼年时就献上谋略。
