Summarise What Makes a Strong Opening Hook

Your openings are fine, which is the problem: nothing makes a reader lean in. This names the one job a hook does in the first sentence or two and three techniques that pull it off, with examples. Good if you are writing, presenting or pitching and the start falls flat. You get a clear sense of how to make people stay.
