Desire

When desire hits you, you will start talking
about it. I started saying, "I'm going to fly one of these days." When I tried flying off that barn, my wings didn't work very well; but they looked pretty good to a four year-old boy with a great desire to fly.
I spoke words that set some cornerstones in my life and caused me to believe it. Eventually, it came to pass.

If you will think back a few years, there are
places you've been and things you've done that you thought you never would do, but you started saying, "I'm going to do that one of these days."
Because there was a desire, you said it over and over until it got down inside you. Then you began to have faith in what you said, and your words increased your desire. That faith maneuvered you
into the position to cause it to come to pass.
