How would you start an essay in Suppose you had the opportunity to teach something you know to someone else?

Here goes:

I want to share with you a secret. It is the solution to one of the most difficult problems students have today, writing. The secret is not a difficult concept to understand, and anyone who can speak and make himself understood is fully capable of mastering its few complexities. It is something many of us do, or similar to, in this world of smart phones and electronic communication devices. It is not even truly a secret, a packet of arcane knowledge. It is actually so simple that therein lies its enigmatic nature. So, are you ready? Lean in close so you miss nothing. The secret to writing is to put Words on paper.

We'll call this the first draft of my essay on teaching something I know to someone else.

What you share in your essay is another matter.

Okay, I'll share one more bit. Get it all down, or as much as you can, then clean it up after. Michaelangelo didn't drop a rough cut block of marble covered in torn up grass and smeared with bull feces at the front porch of the Arte DELLa Lana and tell them, "There's your statue of David." No, he took the better part of three years to clean it up and to chip away more than half of it. You can do a little editing.
