what is your purpose in life?写一篇文章

The title should be What is the meaning of life.
In fact,life is meaningless.You don't chose the date you born and what kind of family you born into.You are just what you are.The society is not for your interests and your imagination and exists for thousands of million years.You should fit into the society rather than the society does for you.
So don't be fooled by someone else's slogans.Be well prepared mentally and physically to face the cruety of reality.
