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. There is a time for departure even when there is no certain place to go. All who seek the roots of life dig in solitude for them. It is never too late to be what you might have been.

The grass is greenest where it is watered. When crossing over fences, carry water with you and tend the grass wherever you may be. Self-image sets the boundaries of individual accomplishment. The difference between doers and dreamers is that the latter wait for the mood before taking action while the former create the mood by acting.

Therefore, they had better aim at something high.
