Several years ago, I worked at a circus. One day, when I was passing the elephants, I suddenly stopped, 41 by the fact that these huge creatures were being held by only a small rope tied to their front leg. It was 42 that they could, at any time, break free, 43 strangely enough, they didn’t. I asked a trainer the 44 for this.
He said, “When they were very young we used the 45 size of rope, and it was enough to hold them. As they grow up, they believe the rope can 46 hold them, so they never try.”
Like the elephants, how many of you believe you cannot do a thing, simply because you 47 once before? Do you often tell yourself “I cannot dance” or “I’m not 48 at math”?
These are 49 of self-limiting beliefs. You must realize you’re 50 for them. A limiting belief that says you’re poor at math has 51 as a reaction to the embarrassing experiences related to math, or the remarks made by someone important to you which 52 you. The cool thing is that because you create the 53 you can choose to change it!
First, 54 it with “I’m good at math”. Once you change your 55 , your subconsciousness(潜意识)will make this come true by driving you to 56 . That might be to take a math course or go online 57 help and so on. Gradually you’ll really see your math skills are 58 .
This is such a simple process that you can 59 it today. Don’t be like the poor elephants and make your life 60 at a place because of a limiting belief you developed years ago.
