You can spend a whole life living below your potential, all because of your beliefs.
An eagle had 4 eggs, until one day an Earthquake shook the nest so hard that one of the eggs fell out. It rolled down the hill a great ways until finally it landed in a chicken coupe.
A few days later the eagle emerged from its shell and was immediately cared for by all the chickens. They taught him to eat like a chicken, talk like a chicken, even dance like a chicken. He was happy.
Then one day he saw a convocation of eagles circling high above. He felt his heart jump. He turned to his best chicken and says, “Look at that! I want to be like them, soaring through the air.” His friend laughs and says, “No, sorry buddy. You’re a chicken. Chickens don’t soar through the air like that.” Unhappy with that answer, the eagle looked for a second opinion. He finds another chicken and proclaims, “You see those eagles, one day, I’ll be up there with them, it is what I was born to do!” “Ha!” The chicken laughs. “Look, I know you are taller than every chicken here, your wing span is double any chicken I have ever known, and heck, you even kind of resemble an eagle. But you, friend, are no eagle. You are a chicken.
So the eagle gave up his dreams, and lived the rest of his days, a chicken.
The Moral of the story is that you become what you believe you will become.
Guard your thoughts, guard your heart, and if you are an eagle, stop hanging out with chickens!
