Sales is a transference of conviction! That's it! If you are deeply convicted about what you sell, no matter if it's cars or critters, it doesn't matter what, you'll prove it through your conviction. Your tone, your demeanor, your body language are all indicators of your conviction. I never had to set an alarm clock when I was coaching football. You never had to convince me or sell me that this was a great thing! I can sell that game to anyone and everyone!
What can you sell? Do you believe it? How deep is your conviction? Your sales will rise with your conviction!
