Envy is part of human nature, but people react to it differently. Those with a broad mind view others' achievements as a direction for progress and treat their strengths as models for learning, constantly improving through appreciation and study. In contrast, those with narrow minds often seek to hinder others. Zhuge Liang's noble character is worth emulating, especially his commitment to 'fulfilling a task once entrusted.' He performed his duties with utmost dedication, never betraying secrets or friends for personal gain. In reality, many abandon their promises for self-interest, which ultimately harms both others and themselves. We should learn from him, working with dedication and living with integrity. Moving from frugality to luxury makes it easy to fall; moving from luxury to frugality makes it difficult to rise. Anger often begins with irrationality and ends in deep regret. Allowing small mistakes to persist leads to major failures; denying one's faults is equivalent to repeating them. Only truly valuable things are worth our pursuit. Remember, the most precious things in life often cannot be measured by price.
