Don’t Tell, Show
“People believe what they see, not what they hear. Always have your presentation, proposals, and prices in writing for the buyer so they can see it with their own eyes. I want you to make this a rule that you sell by: Assume that your buyer, no matter how well you know the person, never believes your words and will only believe that which you can show him. People want to believe you, but you have to help them.” – GC
