Different people have different ways of leading lives.
This does not contribute much to your topic. Start with some idea that gets you to the topic easily. My suggestion;
Different people have different views on how their children be educated.Some people think that their children should spend most of their time on school studies. Whilewhile others think that children should spend most of theirmore time playing.
.... there's no harm in expressing the same topic idea, but rephrase it and present.
As far as I am concerned, if I have children, I probably think that children should spend most of their time on school studies.
... Don't crowd your sentences with the words that mean the same.... That makes them redundant one another and also disturbs its presentation.
Different people have different knowledge and teacher can help them to have a good education.
This does not convey a clear idea.... I think you should rephrase this
When I was a child, the school was benefitedto me to evaluate.
... again , the idea is not clear :(
