Have you ever complained why life is so tiring? Does the sky sometimes seem dark to you? Are your studies sometimes not successful? Well, friend, cheer up and smile all the time．If you see the world with your warm heart, you'll find that the whole world smiles to you．

While in school, sometimes you are tired of your lessons, but have you ever noticed the happy smile on your teacher's face when you did a good job?

One day it is fine．Just before you want to go out, it suddenly starts to rain．Maybe you would feel very sad and start complaining about the weather．But dear friends, why don't you sit down and listen to the free concert that the nature offers you? And with the timely rain, crops in the fields will grow better and better and farmers will have a good harvest．

Although everyone wants to succeed in what he tries to do, sometimes failures can't be avoided．I think failure is not terrible, and the terrible thing is that we are afraid of it and give up hope．When we face failure, we must be confident in ourselves, draw a useful lesson from it and try our best to finish what we have decided to do．As a popular saying goes," Failure is the mother of success．"

Attitude decides everything. With an optimistic attitude life is easy and pleasant. Let's smile to whatever we meet and the whole world will smile to us.
