The world is full of people who will tell you what you can't do. You don't need them. You already know what you can't do. What you need is someone to tell you what you can.
True progress happens when we step out of our comfort zones and embrace change.
What ever you do, do it well. Do it so well that when people see you do it they will want to come back and see you do it again and they will want to bring others and show them how well you do what you do.
你必须完整才能快乐。
数学不仅仅是关于数字、方程、计算或算法:它是关于理解的。
