I have seen human beings who have forged "intellectual" armor to shield themselves from adversity. They seemed stronger than most. They said, "I couldn't care less," and laughed at everything, but when adversity managed to pierce their armor, it caused terrible damage.I have seen human beings suffer from the slightest adversity, the slightest annoyance, but still remain open-minded and sensitive to everything, learning something from each attack.
