Courage is only courage when it is connected to wisdom. It is immature to risk one’s life or health for fun or thrills. Not only is this immature, it is dumb. The Sages ask: “Who is a wise person? One who foresees the outcome.” (Talmud – Tamid 32a)
Driving a car at speeds high above the speed limit because one enjoys the feeling, is stupid. Climbing in dangerous places when one doesn’t have a valid need isn’t courage, but foolhardy. Walking in dangerous places just to prove to others that one is brave is reckless.
Life is too precious to waste it with illusory courage.
