     I once thought that outer beauty is the only factor to become a greatperson.When I was young,  

I read many kinds of books,  most of which described characters who are handsome or beautiful.So

I think that being beautiful is the only way to become a success.

     As I grew up,  the story of my best friend made me realize that outer beauty was not so important

to make a person successful.She was so beautiful a girl that every classmate liked to chat with her,  

but she was very arrogant.In her opinion,  she could get all she wanted because of her beauty,  but all

of her friends left her one by one!Only then did she come to know the importance of the beauty in a

person's heart,  which c hanged her attitude and she made friends again.

     Turning on TV,  we can see many advertisements,  most of which seem to give us a feeling that

physical attractiveness is the most important thing.There_seems_to_be_a_boom_in_plastic_surgery.It

is surprising that more and more people,  especially girls and women,  try it like the first man－made

beauty in China,  Hao Lulu.It is a common sense that attractive people can easily find work.Most good

looking guys usually get higher scores in the job interviews.But,  what is real beauty? I want to say that

is inner beauty because those who have beauty in their soul are really beautiful persons.

     As is known,  the beauty judged with eyes is temporary,  so we should concentrate on inner beauty.

And if we make the efforts to make our minds beautiful,  we'll live a happier life.
