Whatever you're writing — a product page, an email, a post — the first line has one job: make the second line get read. Fail there and it doesn't matter how good the rest is, because nobody reaches it. The opening is where most writing is quietly lost.
Open with them, not you
Start with the reader's problem, desire or curiosity — not your intro, your context, or a warm-up. 'Still losing sales at checkout?' pulls a reader in. 'In today's fast-paced world…' pushes them out. Earn the second line by being about them from word one.
Cut the throat-clearing
Most first drafts start a paragraph or two before the actual point. Find where it gets interesting and delete everything above it. Your real opening line is usually hiding in the middle of what you first wrote.
