How do you write a 750 word essay on how to persuade your instructor that all people should master this certain skill?

Is it any skill you want? Or an assigned one?

If it's any skill you want to write about, then write a list of pros and cons of mastering that skill. If the cons outweight the pros, then I wouldn't do that topic.

If it's an assigned skill, then ignore the cons. Start with your introduction. You think everyone should master this skill because.... Write a few sentences that summarize the points you're going to make in your essay.

Write down a list of all the pros you can. List those in the body of your essay and within those listings, explain descriptive scenarios and how it might be a positive thing.

Closing paragraph, recap what you proved in your essay trying to make it sound different then your introduction paragraph.

Good luck! 750 words is a killer!
