The lesson
Open a list post with the one credential that earns it, then give each tip an imperative title and a short reason.
The post starts "I've been the first marketer at two companies now worth over $2 billion." It lists nine numbered items, each a command heading such as "Create the problem" or "Look bigger than you are". It ends with "If you've done this - what would you add?" above a photo of her at a desk.
Don't borrow the credential. You need your own. Keep the shape: one line of proof, a number in the opener, short imperative titles, and a question that asks readers to add theirs.
