A person who really manages his own life is like a person who can herd sheep. A shepherd will never lead a sheep, and the whip will always fall on the last sheep. Why? No matter how fast the first sheep runs, the ones behind will always fall behind. If you catch up with the latter, the overall speed of the flock will not be too slow. Therefore, the most important thing in life is to see clearly what your shortcomings are. Ambitious people in life never get the highest score, but look at the lowest score.
