I can't write you an entire essay dude...but i can help you with it.
In the introduction sum up what you are going to talk about it...The first thing you write in your introduction should be your hook, a hook is something you catch the readers attention with. it is usually a question.
For the body paragraphs explain a point and give examples.
your final paragraph should conclude what you wrote, your not trying to prove anything just to sum up everything, re state your points and conclude with a catchy ending.
I hope this helps.
