I saw a cartoon in a recent New Yorker magazine in which two people were finishing their dinners at a Chinese restaurant and had just opened their fortune cookies. One fortune read, “You are going to die.”

If you let this fact sink in — that life is short, and we all die — it can actually act as a powerful motivating force to help maintain focus and priorities. Everything changes and is impermanent, so are we fully present and making the most of this fleeting moment? Are we fully aware of what we are doing? Appreciating impermanence clarifies priorities, and it helps us identify any frenetic, shallow and ineffective activities we’re being distracted by. We see clearly the things that exhaust us and distract us from experiencing the blessing and opportunity of each particular day.

In Zen practice it is often said that the span of our lives is like a dew drop on a leaf — beautiful, precious, and extremely short-lived. Life is remarkably unpredictable. Whatever you want to accomplish, whatever is important to you, do it, and do it now — with as much grace, intensity, and sense of ease as you can muster. None of us knows what life will bring. In any moment everything we take for granted can change. We must be careful not to dwell on impermanence constantly, to the point that we become paralyzed with fear of loss, but we can use an awareness of change on a deep and wise level to focus our priorities and increase our appreciation of the sheer beauty of existence.
