I'm a catalyst for change... You can't be an outsider and be successful over 30 years without leaving a certain amount of scar tissue around the place.

The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all. And that, of course, causes great confusion.

Innovation without practicality is just noise—farmers need real solutions.

唯一能让你明智的是你自己的经验。

真正快乐的唯一途径是接受自己，并不断成长和进步。
