Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something and that this thing must be attained.
A mathematician's work is to find patterns where others see chaos.
没人会和你自己一样对你所拥有的东西印象深刻。（Morgan Housel《金钱心理学》里面的一句话，可以理解为禀赋效应：即，由于情感上的偏见，人们在自己已经拥有的东西上比尚未获得的东西拥有更大的价值）
No one is as impressed with your possessions as you are.
