Balance righteousness and profit by understanding both their boundaries and their synergy. By prioritizing morality while pursuing interests, one can guide profit through righteousness and transform private interests into public good—this is the true path of life. Self-restraint is a sign of maturity. Without it, one struggles to endure hardship and failure, making it impossible to shoulder great responsibilities. Diligence is a skill cultivated over time, not just an attitude; it involves performing small tasks with care and learning from feedback. While power can elevate you to the summit, it cannot grant true happiness. Success achieved through flattery or coercion is fleeting and leads to eventual exhaustion. One can be unique without being eccentric. Persistent resentment reflects spiritual poverty. While a healthy sense of dissatisfaction drives progress, endless greed seeds suffering. Ignoring small mistakes leads to great failures, and denying faults is tantamount to repeating them. In social interactions, people often show only their best sides initially, but true character is revealed through time. Real friendship is seeing each other's flaws, yet choosing to stay by each other's side.
