You may be under the strict impression that an essay is extremely rigid and has to abide by the template. However, if you keep open your creative milk and churn your piece with it; you can take different streaks. There are more ways than to color your hair!
The best and most effective way, of course, is the fish-type. Here, you begin and end with similar-sized paragraphs and leave the meat in the middle. The beginning invokes interest and the end gives it a sense of authenticity. What happens in the middle is life.
You will need to jot down the most seminal and effective points and speckle the Body (the meat segment) with it; you may also add a few resonant examples. People love to read about illustrations.
You may also present your piece in a singular flowing motion; snake-type if you will. Here, the paragraphs will take energy from the previous one and go ahead, as if in a torrent. The release actually happens in the last paragraph. This is the preferred mode for reflective or narrative pieces. You should not pause and cause hiccups. Of course, you need to work on your writing style as well.
Another way to organize your piece is to retreat into past. This resembles the hook-type. Here, you can ignite the readers into a brush with your past through the introduction and then explore territories hidden in your old life story. You will have to be careful to leave scopes to return to the present and also to keep the piece relevant and strategic.
While writing official pieces, you need to give impressions to each paragraph with emphasis and bullets. This resembles the field type. You will have to be well-versed with the texture of the piece and significance of each segment to do full justice to it. Your style should have a professional edge to it.
Of course, there may be special pieces; say a full report on a famous personality. Here, you can develop your own type and work on it to inspire the readers. With essays, what matters most is your will to impress, innovate and absorb. You cannot stagnate; you need to keep thinking of smart ways to flatter the ones who go through your piece.
Passion is the key! Ingratiate it.
