Future Planning Metaphor

This morning I heard a sermon on the TV in my hotel room near the Paris airport. It was the Hour of Power from the Crystal Cathedral. Robert Schuller's son talked about painting a map of your future in oils not in water colors. I was very impressed with this metaphor: with water colors, you need to be very precise and the results are fixed and permanent...nearly impossible to change; with oils, you can experiment, scrape off what you don't like, or paint over it after it dries.
