Beginner Writer Question; I have never written an essay in my life

I have never in my life ever written an Essay, I don't even know how to start, or even if there is a header to it. Please help, should there be anything at top center of the first page?

Good afternoon.

What is your prompt/assignment?

my assignment : Mastering a Skill

I am to think of a skill that most do not have but could benefit from mastering. Why would people benefit from having this skill? What are the consequences of not having this skill?

Write a 750 word essay to persuade my instructor that all people should master this skill.

OK, so what skill(s) are you thinking about using as your topic? What kinds of skill(s) is/are this/these to be? Athletic skills, mental abilities, personality strengths? What are you thinking?

Well, I was thinking about how everyone should learn how to use a computer.
because most times you need one to do anything these days.
