Passion Enthusiasm Confidence

A new vacuum cleaner salesman knocked on the door on the first house of the street. A tall lady answered the door.
Before she could speak, the enthusiastic salesman barged into the living room and opened a big black plastic bag and poured all the cow droppings onto the carpet.
"Madam, if I could not clean this up with the use of this new powerful vacuum cleaner, I will EAT all this cow poop!" exclaimed the eager salesman.
"Do you need chili sauce or ketchup with that?" asked the lady.
The bewildered salesman asked, "Why, madam?"
"There's no electricity in the house..." said the lady

There is nothing that beats being passionate about what you're selling and feeling confident in your product.  But how can you be passionate about a refrigerator, a vacuum cleaner or an air compressor?
Passion and enthusiam come when you're confident, when you know your product inside and out and when you truly believe that your product can solve your customer's problem.  This all starts with product knowledge and product belief.  Whether you're selling cars, refrigerators, air compressors, lights--whatever, you need to know everything about your product and why it's better than anyone else's.  If you don't believe in your product, your customer will see this and you will not make the sale.  Although his approach may have been a little over the top, the vacuum cleaner salesman in the joke believed in his product.
Without passion, enthusiasm and confidence, sales becomes a tough job and not a joy.
