The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
爱是什么样子?它有双手来帮助他人。它有双脚匆匆赶往穷人和需要帮助的地方。它有眼睛看到痛苦和贫困。它有耳朵听到人们的叹息和悲伤。
Mathematics is the poetry of logical ideas.
The world is a plot, a conspiracy, a cabal.
Experience is simply the name we give our mistakes.
