Feeling sad because a competitor has succeeded in wealth, fame or other good things, and at the same time striving to improve oneself in an attempt to match or surpass the other party, is called jealousy. 2. Life is a rich feast, but some people would rather go hungry. 3. It is the common practice in the world for a saint to hold one in his arms. It is not self-seeing, so it is clear; it is not self-righteous, so it is manifest; it is not self-cutting, so it is meritorious; it is not self-conscious, so it is long-lasting. My husband does not fight, so no one in the world can fight with him. 4. Everyone should have self-esteem, self-confidence, and independence, otherwise they will be slaves, but self-esteem is not contempt, self-confidence is not complacency, and independence is not independence. 5. So when you are bored and thinking wildly, please remember that you have thousands of troops in your hands; you are their commander. When reviewing them, you might as well ask yourself whether they played their maximum role in the battle.
