Hope is not a feeling; it is a doable thing.
希望不是一种感觉；它是一种可行的事情。
We teach a subject not to produce little living libraries on that subject, but rather to get a student to think mathematically for himself.
译文：修性养心最好的方式就是少些欲望，培养廉洁的美德最好的方式就是不要心存贪念。赏析：人的欲望太多，贪念过盛，一旦无法满足，就会伤身费神。守身必谨严，养心须淡泊。为了追逐名利，有的人忘乎所以，最终走上违法犯罪的道路。
The only thing that counts is what cannot be explained.
"Success is nothing if you don't have the right people to share it with."
