After a few years of success, salespeople might start feeling depleted and burned out. They might complain about the futility of the rat race. What happened to the hope, anticipation, and determination that made selling so exciting in the early days? The answer is simple: These salespeople ran out of fuel. If you find yourself only running on two cylinders, check your reservoirs and replenish them today. It may surprise you, but all the fuel you'll ever need to reach the highest peak is already stored within you. It's up to you to release the valve that will let it flow.
