幸福不仅仅是悲伤的缺席；它是意义的在场。
Happiness is not just the absence of sadness; it's the presence of meaning.
科学不仅仅是事实的集合；它是一种思考方式。
举一个例子尚且不明白，就不要追求见多识广。
The man who is fit to work at any particular trade is unable to understand the science of that trade without the kindly help and cooperation of men of a totally different type of education.
你停止尝试变得更好的那一刻就是你开始变得更糟的那一刻。
对幸福的追寻是不幸福的主要原因之一。
I don’t let mistakes discourage me, I let them educate me.
The best way to predict the future is to implement it.
