You are the artist, your life is the canvas.  You are the playwright and your life is the script.  Life is like a movie.  As I have previously mentioned we play the script over and over in our minds.

Now think about this. If you keep creating the script (thought) in your mind, the results will be just as you you have rehersed it.

The way to change this is begin to recreate this script,

changing the chactaristics  little by little.  By doing this in your mind, you will begin to change the physical outcome and results of the given situation. I guest you can call this, changing the script.
