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:

First,       it with “I am good at math”. Once you change your      , your subconsciousness will make this      by driving you to act. That might be to take a math course or to go online       help, etc. Gradually you’ll really see your math skills are      .

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.
