You can't teach a kid to ride a bike at a seminar

David H. Sandler was a salesman who hated everything about the typical sales process. He hated making cold
calls and giving presentations only to discover prospects did not have the money or authority to buy his products.
He also disliked waiting for prospects to make up their minds about buying, because he knew the prospects
were using their time to approach other suppliers to find better deals. Sandler decided to turn the sales process
on its head and put the salesperson, not the buyer, in control. He wrote You Can’t Teach a Kid to Ride a Bike at
a Seminar to explain the Sandler Selling System more than 40 years ago, and in this updated edition he continues
to offer timeless sales training and coaching advice.
