Where does Fear come from?
That's a good question. Fear can come from many sources. Sometimes it comes from watching a fall and being afraid you're going to do the same thing. Some-times it comes from a fall you have taken or an injury that was scary and painful. Fear can also come from the wipe-outs we create in our minds! Fear can be very sneaky. It can rear its head when we are burned out, feel too much pressure, or want to try other sports besides gymnastics. No matter what the source of fear, what results are negative thoughts. Most often when you are afraid, you begin this tirade of negative thoughts. You may say to yourself things like, "I'm going to fall," "I can't do this," and "I'm going to peel off the bar and go flying into the wall!" Of course, when you say these things to yourself over and over, you feel very afraid. So afraid in fact, that you feel you can't push through it. These negative thoughts are like a run away train. They feel out of your control. But actually they aren't, because you control the thoughts in your head! When your thinking is negative and out of control, the result is fear, stress, balking, and tears.
