Know yourself: what a scary thought. It’s so much easier to sit in judgment on other people than to carry out a hard-headed analysis of your own strengths and weaknesses.
Only by following the Dao can you shed your self-centeredness and “conquer” yourself. This is a long and arduous process, but it is the only way you can truly know yourself and achieve contentment.
People who know others are intelligent;
People who know themselves are enlightened.
People who conquer others are strong;
People who conquer themselves are mighty.
People who are contented are wealthy.
People who persevere have willpower.
People who do not lose their roots endure.
People who die but are not forgotten enjoy longevity.
