School is the best preparation for our working life.

Every child must go to school. If he or she wants it or not they have to study and graduate at least secondary school. Why? Because in my opinion school is the best preparation for our working life.
To start with, it is very important to work and co-operate with other child, because when they grow up and start working in a company they will have to capture cooperate skills.
School professes children how to be open in relations with other people.
What is more, children are taught responsibility and tolerance towards others. In adults life everyone should be responsible for their deeds. Through tests, homeworks and many activities school gives children a sample of hardworking life.
As opposed to the above ideas some people think that school isn?t beneficial for all children, because it teaches them how to rival one another. In my opinion this skill is important, because nowadays we have to rival to get better marks, jobs, etc.
All in all, I strongly believe that school is very useful and that it?s giving the best preparation for working life.
