The pursuit of mathematical truth is a pursuit of beauty, elegance, and simplicity.
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.
别到处说世界欠你一个生活。世界什么都不欠你。它比你先存在。
Stay true to yourself and never let anyone dull your sparkle.
