Most people are bad at taking action. At night, they imagine a thousand paths; in the morning, they simply roll over and keep lying there.

They don't understand that taking immediate action—when you think it, do it—is the key to starting strong in life.

The other group doesn't have the above problem, but they tend to fall into complacency. After succeeding at one thing, they think they can do anything. After years of success, they feel they've eaten more salt than others have eaten rice, so they start getting arrogant and careless.

Actually, sustaining a career is simple. It's what Zhuge Liang demonstrated: be confident when you're young, know the world is divided into three before leaving your thatched cottage, dare to act, grow through action, and self-correct as you go. After long success, stay humble—understand that, as the oil seller said, it's nothing but practice makes perfect.
