When you feel sad and in pain, the best thing to do is to learn something. Learning will help you stand on invincible ground.
Dreams should not be too deep, for depth makes waking difficult; words should not be too full, for fullness makes smoothness hard to achieve; tones should not be set too high, for highness makes harmony difficult to reach; affairs should not be handled too decisively, for decisiveness makes retreat and advance hard to manage; emotions should not sink too deep, for depth makes self-extraction impossible; profit should not be valued too heavily, for heaviness makes clarifying one's ambition difficult; people should not be too fake, for fakeness makes sincere interaction impossible; the world should not be seen too clearly, for clarity makes action difficult.
Changing a consumer's inherent mindset is harder than climbing the sun, yet it is not impossible.
Seize the opportunity and be in the right place. Do what you love, and love what you do. Survive as a lifelong learner. Do not expect others to thank you; keep your eyes wide open at all times.
In a miraculous life, Success is inseparable from persistence and love, while failure is often accompanied by deep reflection and a rise to new heights.
