I’ve realized that the most important thing is to be happy with yourself.

The future of life on Earth depends on our ability to take action. Many individuals are doing what they can, but real success can only come if there is a change in our societies and our economics and in our politics.

You could be the most beautiful person in the world and everybody sees light and rainbows when they look at you, but if you yourself don't know it, all of that doesn't even matter.

It’s not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.

教师最重要的是一颗理解的心，它值得无限地尊崇。人们在回忆中赞赏才华横溢的教师，但感激曾触动自己的人类情感的教师。对于成长中的孩子、对于孩子的灵魂，功课是必须的，但至关重要的营养是人性的温暖。
