Use the smile to change the world. Don‘t let the world change your smile.
用你的笑容去改变这个世界，别让这个世界改变了你的笑容。
Always keep a smiling face toward the world, maybe it can return you a warm smile sometimes, especially in such cold days.
But it is really cold these days, and the chilling wind makes me feel very bad.
I really hope that the weather could be a little comfortable.
Work and struggle and never accept an evil that you can change.
努力奋斗，坏事若是有改变的可能，就绝对不要认命。
From Andre Gide.
If you think you are beaten, you are; if you think you dare not, you don‘t.
If you‘d like to win, but you think you can‘t, it is almost a cinch, you won‘t.
If you think you will lose, you are lost.
For out in this world, we find success begins with a fellow‘s will.
It‘s all in the state of mind.
If you think you are outclassed, you are.
You have got to think high to rise, you have got to be sure of yourself before you can ever win the prize.
Life‘s battles don‘t always go to the stronger or faster man, but sooner or later the man who wins is the one who thinks he can.
So, please struggle to acquire an unshakeable belief in yourself.
Everyone will know how to compile a program perfectly if there are some tutorials to follow.
If there is no such tutorial, or there is no precedent for what we are doing now, I think it is a rare chance for us to demonstrate our capabilities and to improve oursleves.
