I was struck by the lack of testimonials, and this...
"hundreds of strategies, tactics, and ideas that you can choose among and easily put into practice."
I would suggest this is your problem. People don't want hundreds of things that might work they want
the one right way for them. You need a way to explain the buyer isn't going to try one technique after another for the next two years.
For example, a diet plan. Why do people try, on average, 4.7 diets before they find one that works for them? Body chemistry. Our plan is based on the six types of body chemistry, each with its own weight loss plan.
....And with our plan you get this little kit to instantly tell which body type you are. Simply swab the inside of your mouth. Put it in this vial of chemical, and it will change color. Our book is color coded, so you use only the techniques and strategies right for you.
In other words, people don't want hundreds of tactics, strategies and techniques. They want one -- the right one. What I just showed you is how you take this overwhelming amount of data, 99% irrelevant, and manage it so the user gets what they want within seconds.
Next this sounds like your solution, and you're not an expert. So it comes off sounding like a system which has succeeded in curing insomnia one time, total. It's far too easy to dismiss with a "well it worked for you but will it work for me?"
People think these "here's my story" letters somehow makes people believe you. It doesn't. You've got to show it works for other people, not just you. This is all sentence after sentence of completely unsubstantiated claims.
