3. The time to catch up is gold, but the water that cannot catch up is running water. -Proverbs
4. Be ambitious, be virtuous, never lust, abandon doubt and stagnation, so that a few ambitions can be revealed and felt; Endure flexion and extension, remove details, ask questions extensively, except being too stingy. Although I have stayed for a long time, why bother to harm the beauty, why bother to suffer it? If the ambition is not strong, the intention is not generous, but it is stuck in vulgarity, silently bound in feelings, and always curled up in mediocrity, it will inevitably be vulgar. -Zhuge Liang
