Prime numbers are what is left when you have taken all the patterns away. I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them.
知足的人不因利禄累害自己。
Be yourself, don't change yourself to please others.
I don't want to be a product of my environment. I want my environment to be a product of me.
The art of progress is to preserve order amid change and to preserve change amid order.
