Imagine you only have one year to live. What important things would you be doing?
How would you be allotting your time to accomplish the most you could? This exercise is one method of going after your priorities. That which does not kill us makes us stronger. Do or do not. There is no try. The grass is not, in fact, always greener on the other side of the fence. No, not at all. Fences have nothing to do with it.
The grass is greenest where it is watered. When crossing over fences, carry water with you and tend the grass wherever you may be. Every man takes the limits of his own field of vision, for the limits of the world. Some people walk in the rain. Others just get wet.
