“Good thinkers are always in demand. A person who knows how may always have a job, but the person who knows why will always be his boss. Good thinkers solve problems, they never lack ideas that can build an organization, and they always hope for a better future. Good thinkers rarely find themselves at the mercy of ruthless people who would take advantage of them or try to deceive them, people like Nazi dictator Adolf Hitler, who once boasted, “What luck for rulers that men do not think.” Those who develop the process of good thinking can rule themselves – even while under an oppressive ruler or in other difficult circumstances. In short, good thinkers are successful.
I’ve studied successful people for forty years, and though the diversity you find among them is astounding, I’ve found that they are all alike in one way: how they think! That is the one one thing that separates successful people from unsuccessful ones. And here’s the good news. How successful people can be learned. If you change your thinking, you can change your life!”
-John C. Maxwell (How Successful People Think)
