The classic example was as follows: There was nothing in this world that could stop mankind from advancing. Death is not scary, what is scary is being forgotten. There was only one person who could truly save the world, and that was himself. In this world, nothing is eternal, only time is the most precious. Everyone has their own different life trajectories. We can't change the past, but we can control the future. Nothing in this world is more precious than love. Courage is not being fearless, but being firm in the face of fear. Success is not the end, but a long journey. In this world, you can only get rewards by giving. Everyone has their own dreams. Only by persistently pursuing them can they be realized.
