About 10 years ago， I started a job as a trainer . In one of my first classes， the head trainer told a very     story that I would like to share with you.

     He began by drawing a   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   his idea， "the world?" The trainer said， "That's close and this is your Comfort Zone. Inside your circle you have all the things that are     to you. Your home， your family， your friends and your job. People feel that inside this circle they are safe from any     or conflict. "

     "Can anyone tell me what happens when you step     this circle?" A strong silence came over the room. The same eager guy announced， "You are afraid. "     guy said， "You make mistakes. " The silence continued and the trainer smiled and said， "When you make mistakes，     can the result be?" The first guy shouted， "You     something. "

     "Exactly， you are learning. " The trainer turned to the board and drew an arrow    from the man directly to the outside of the circle. He continued to say，  "When you leave your Comfort Zone you put     out there， in front of the world to be in situations that you are not     with. The end result is that you have learned     that you did not know and you expand your knowledge to become a better person. "  He turned again to the board and drew a     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    be able to expand your horizons and learn. When you step out of your Comfort Zone you will finally make your circle bigger and your mind grow stronger， and all in all a better person. "
