I went to the woods because I wanted to live deliberately,I wanted to live deep and suck out all the marrow of life, To put to rout all that was not life, and not when I had come to die, Discover that I had not lived.

The game of life is the game of everlasting learning. At least it is if you want to win.

质量从来不是偶然的；它始终是智慧努力的结果。
