I always make sure that I do not heedlessly compare myself with something beyond my reach. If I do make such a comparison, I make sure that I study that person?s advantages and strong points, and not compare my situation with that person?s overall talents and wisdom. Most of the time, I simply compare my own course of development: Have I made progress today compared with yesterday, and will I do better tomorrow than today? In this way, I continually challenge myself and surpass myself.
