Do every duty， and expect no reward for it.
尽一切职责，而不希望得到任何回报。
唯一的限制是你给自己设定的限制。
I don’t play for records. I play because I love the game.
创新是可持续农业的关键。
Those who do not remember the past are condemned to repeat it.
I will hazard a prediction. When you are 80 years old， and in a quiet moment of reflection narrating for only yourself the most personal version of your life story， the telling that will be most compact and meaningful will be the series of choices you have made. In the end， we are our choices. Build yourself a great story.
I don’t let anyone define me. I define myself.
