I used to work for a telemarketing company when I was 18 selling long distance. About 20% of the people cursed me out as they did not want a telemarketer calling their house. That job was not fun but it helped me get over my fear on the phone. I owe a lot to that job and in life we can attribute a lot of our growth to the times where things were NOT that fun.
Influence – John C. Maxwell says that a leadership is influence, nothing more and nothing less. Everything rises and falls on leaderships, so it’s an essential attribute for success.  Influence is also used to effectively and persuasively communicate the virtues of a good product or service, and to get people to say YES!  We also know that at sales.
