The only constant in agriculture is change—embrace it.

【譯文】 孔子說：“年輕人應(yīng)該孝順父母，尊敬師長，認真誠信，廣施愛心，親近仁人志士。能輕松做到這些，才可以從事理論研究。”

I did not write half of what I saw, for I knew I would not be believed.

Agriculture is the foundation of civilization, and we must invest in its future.

I've always been very driven and ambitious. I've always wanted to be the best at whatever I do.

我們學(xué)得越多，就越意識到我們不知道的還有很多。
