Recently, social scientists made an amazing discovery. The mind cannot tell the difference between mental imaging and actual physical practice. If you visualize in your mind's eye that you are doing a thing, the mind cannot distinguish it from you actually doing what you visualize.
Athletes have learned this. If you see yourself hitting the ball, it helps you hit the ball. I am not saying that batting practice doesn't help. It does. But part of success in sports is between your ears, and this part can be accomplished as well by visualization as it can by practice.
Each of us needs to learn to visualize what we want. See the blueprint in your mind. See yourself completing the task. See it as already accomplished.
Jesus said, "As you believe, so shall it be done unto you."
