Selling cables is easy!

The secret to your success:

”When you're selling to a customer, you're doing him a service: You're giving him the opportunity to buy something that will contribute to his musical enjoyment, and you're providing him with the benefit of your expertise in helping him to select the components or system that will be best for him, given his tastes, preferences, listening environment, and budget.”

All successful salespeople believe what they are telling the customer. Does that mean the customer should believe it, too? I think the customer should be a little skeptical.
