The true measure of success is not in the harvest, but in the legacy we leave behind.

The key is to stay focused on your own path.

I am only resolved to act in that manner, which will, in my own opinion, constitute my happiness, without reference to you, or to any person so wholly unconnected with me.

The truth is rarely pure and never simple.

The best way to learn is by doing.

生活中唯一真正的失败是不忠于自己所知道的最好的东西。
