Take a plain index card. Turn it to make its vertical 5" long. Start to write:
Identify your topic on the title. Write three sentences. Space the paragraph, rewrite three sentences.
Reaching the bottom of the card, there should be five paragraphs. Five paragraphs, three sentences. Memorize: 5x3 on 3x5.
One side of an 5x3 index card should be enough for an essay. If not, take two index cards. If that's not enough, think again.
This post fits on one 3x5. Some space is left. This last sentence is intentionally added to follow my own rule.
