You are once a chronic gambler but with the help of a professional you are now totally cured, then a publisher offers you to publicize your journey from being a chronic gambler to a cured one, but of course, everything could be exposed like your habit experiences, your agony and even your personal life, will you agree to do this, of course the publisher will pay you for the story that you are going to provide.
It's always better to accept your situation and share your mistakes so that other may not fall on the same ditch. It's okay to talk about the bad things you left behind.
But it's also really difficult to say when you are not actually in that situation. The payment seems to be good when you haven't walked on their shoes and things would be different depending on the environment they are from and the family they are in.
