Oh, I've seen this before - the author who thinks their way with words automatically translates into ad copy that sells. It's like a painter assuming they can do graphic design because they know which end of the brush to hold.
Look, writing a novel means you understand narrative arcs, character depth, and pacing. Advertising is a completely different beast. You've got maybe three seconds to stop someone's scrolling thumb. Every word has to earn its place, and "elegant prose" often just gets in the way. That beautiful metaphor you spent hours crafting? Dead on arrival if it doesn't drive a click or a conversion.
The shift is possible, but you need to kill your darlings. Start reading every ad that makes you stop - not the ones you like, the ones that work. Study the headlines, the urgency, the pain points. Then rewrite your own work with a machete. Cut the adjectives, sharpen the verbs, and ask yourself: "Would this make someone in their pyjamas at 11pm tap 'buy now'?"
And please, lose the snark about knowing the alphabet. That attitude screams amateur hour. In this world, you're judged by the results, not the vocabulary. If you're serious, come with curiosity, not ego. Happy to answer questions if you've got specifics - but leave the hot shit at the door.
