I could imagine the next time I'm with a young child identifying a bad attitude about to form. While I was mowing, I was thinking of a great way to show a child the consequences of his decisions. With the m ower in gear, zigzag carelessly, overlapping, swerving, and making a very visible mess. Then talk about how the path shows clearly exactly what was done. Each decision to turn, go, or circle is clearly visible.
Life is like that.
Every decision we make has consequences. Our life is a path reflecting the decisions we've made one by one. Then you could talk about how the mowing is really done - by following where someone went before. You keep one tire in line with the previous path. In life, if we keep following a reliable guide, we'll save ourselves immeasurable difficulties.
