John C. Maxwell: "A man must be big enough to admit his mistakes, smart enough to profit from them, and strong enough to correct them."

Never stop being a student.

Never stop learning, because life never stops teaching.

Never stop reinventing yourself.

No setback is permanent unless you make it your address.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.

Not every closed door is a rejection. Some are redirections.
