There is no virtue in being uncritical; nor is it a habit to which the young are given. But criticism is only the burying beetle that gets rid of what is dead, and, since the world lives by creative and constructive forces, and not by negation and destruction, it is better to grow up in the company of prophets than of critics.
Carefully watch your thoughts, for they become your words. Manage and watch your words, for they will become your actions. Consider and judge your actions, for they have become your habits. Acknowledge and watch your habits, for they shall become your values. Understand and embrace your values, for they become your destiny.
