How to sell people anything: tell them you have a secret tip that will make them richer/thinner/happier. But the real, REAL secret is that there's no secret and all the knowledge you could ever need is already available for free. What's NOT available for free is support, coaching, helping you pinpoint where you need help, where you need to change something. And tat's not something you get from an online course. Don't buy a course if you can buy access to personal support.
