Remember, an overcast sky does not necessarily mean rain. In life, we encounter many people, but few truly understand us; in daily life, we know many, but few rely on each other. The world is not short of people to talk to, but we long for a friend who understands and reads us. Among the masses, we are not lacking in acquaintances, but we seek a companion who suits us and empathizes with our feelings. Understanding a single key principle can benefit you for a lifetime. In life and work, never be too greedy. Small favors accumulated can create a huge void. If you accept help, always look for an opportunity to reciprocate. The wind that blows in spring leads to the rain in summer; giving is for receiving. It is simply a relationship between seeds and fruits. Do not be harmed by naivety. Remember: Life is like a play where everyone seeks a balance of interests. Only a balanced game can last. Patience is the abbreviation of perseverance and endurance; learning is the summary of hard study and diligent questioning. Success is at your feet, and happiness is in your heart.
