Years ago, I worked at the Ringling Brothers Barnum & Bailey Circus. One day, as I was passing the elephants, I suddenly stopped, by the fact that these huge creatures were being held by only a small rope tied to their front leg. It was _that they could, at any time, break free, strangely enough, they didn’t. I asked a trainer the for this.

He said, “When they were very young we used the size rope, and it was enough to hold them. As they grow up, they believe the rope can hold them, so they never try.”

Like the elephants, how many of you believe you cannot do a thing, simply because you once before? Do you often tell “I cannot dance” or “I’m not good at math”?

These are of self limiting beliefs. You must realize you’re for them. A limiting belief that says you’re poor at math may have as a reaction to the embarrassing experiences related to math, or the remarks made by someone important to you which you. The cool thing is that because you create the ___you can choose to change it! Here is how:

This is such a simple process that you can it today. Don’t be like the poor elephant and make your life at a place because of a limiting belief you developed years ago.
