If we use a little imagination and the technology at our hands, we can turn our current group of contacts in our phone into evangelists for our business.

Scott Hamilton wrote in his book Finish First that one principle to winning is simply this: Outwork Everybody! Now you can do it this week and build on it from week to week!
