Teaching receptive everyday people of the world (at their pace, usually within 6 to 12 months) to be high-level, quality, all-around, rock-solid, Rolls Royce type leaders of upstanding character.  Guaranteed!

Then list out each feature and benefit in a brain storming type manner.  Take the time to do this and keep adding as you discover more to add.

Then organize them based on importance.

I proved this time and time again.  In the insurance business, the normal closing average in my former industry was 50 % to 60 % within a few months of starting selling.  

It took me longer to get started simply because I analyzed the whole thing.  My closing average was in the 70 % range.  The normal placed rate was 60 % to 70 % range.  My placed rate was 88 %.  My sales volume was almost 150 % higher than my peers.  What am I saying?

Take the time to analyze the product or service and KNOW it.  Then tailor it to your customers.  Then create the presentation accordingly.  By the way, I was trained in insurance sales to get in and get out in 90 minutes and get a check.  May times I was in homes 2 and 3 hours because it was appropriate to be in the home 2 and 3 hours.
