Don't despise the little things
When trying to accomplish big things, we must value every minute. We have to make an exceptional effort to maximize all that we do. Training ourselves, others, prospecting, and all else should be maximized in every instance. Every little thing must be focused on because out of these little things evolves massive success. The best "customer" is the person that is actually a member of your team. They must be taken care of at all costs no matter how small their efforts may seem. Think about this: "Dinosaurs became extinct but rabbits still abound."
