Did you know that everytime you influence another person to do a better job, you benefit that person and increase your value? Clearly I'm speaking about a positive influence. Someone once said that no one can really motivate anyone else; all we can do is motivate ourselves and hope it catches on. You will probably never know how much you influence others with your behavior.
When you always go the extra mile, you will influence those in your circle of friends and acquaintances, your family, your co-workers, and ever your bosses to do more and better than they have done before. Your value to yourself and others is greatly enhanced by your ability to influence others to be happier, more productive people. There are no salary caps or career limits for those who lead others to great heights of success. Such people are simply too valuable!
Sometimes this is as simple as just telling someone thank you and how much you really appreciate them. For me, I like starting my day out this way. It gets my blood pumping and energy flowing. Team work!
