The lesson
Put the product mention late in a story post, then return to the emotional point so the last line isn't the pitch.
"I spent 16 years succeeding at the wrong thing." opens a post of one-line paragraphs: "Big title. Big salary. Completely empty.", a "Two years later:" list, then "Want to do the same? Use my playbook" with a link. It returns to "Failure stings. But empty success? It suffocates. Choose wisely." A black card repeats the idea.
Don't copy his income and hours claims, which are personal and unverifiable for anyone else. Keep the one-sentence hook, the short lines and the pitch placed between two emotional beats.
