From an early age, it's so easy to fall into the habit of comparison. We learn it from the start: big versus small, fast versus slow, black versus white.
Comparisons in themselves are not wrong, they are statements of how we perceive the world around us. We can embrace comparisons for what they are without letting them affect how we feel about ourselves or about others.
More importantly, we each have our strengths and weaknesses. So just as the Ox exhibits strength in one way, there is still much he can learn from different strengths of his companions. We each have our unique way of sharing our little wisdom. We are all teachers. We are all students.
