     About 10 years ago, I started a job as a trainer for a telemarketing agency. In one of my first

classes, the head trainer told a very inspiring story.

     He began by drawing a stickman standing in the middle of a circle. To make it more interesting,

he drew things like a house, a car, and a few friends inside the circle.

     He asked the question, "Can anyone tell me what this is?" In a long silence, one guy decided to

throw out "the world?" The trainer said, "That's close and this is your Comfort Zone. Inside your

circle you have all the things that are important to you. "

     "Your home, your family, your friends, and your job. People feel that inside this circle they are

safe from any danger or conflict. "

     "Can anyone tell me what happens when you step out of this circle?" A strong silence came over

the room. The same eager guy abruptly announced, "You are afraid. "

     Another guy said, "You make mistakes. " The silence continued and the trainer smiled and said,

"When you make mistakes, what can the result be?"

    The first guy shouted, "You learn something. "

    "Exactly, you are learning. " The trainer turned to the board and drew an arrow pointing from the

stickman directly to the outside of the circle. He continued to say, "When you leave your Comfort

Zone you put yourself out there, in front of the world to be in situations that you are not comfortable

with. "

     "The end result is that you have learned something that you did not know and you expand your

knowledge to become a better person. " He turned again to the board and drew a bigger circle

around the original circle, and added a few new things like more friends, a bigger house, etc.

     "The moral of the story is that if you stay inside your Comfort Zone, you will never be able to

expand your horizons and learn. When you step out of your Comfort Zone you will eventually make

your circle bigger and your mind grow stronger, and all in all a better person. "
