A good idea, properly understood, always has a practical application.

Common Knowledge and Common Sense, most have one or the other, I just happen to possess both.

Do not confuse good tactics with good luck.

Why is it that common sense is seldom common practice?

Just because it's common sense, doesn't mean it's common practice.

A person who has intelligence understands that the knowledge can only be acquired, not common sense as that is already inherently employed and invisibly wired in everyone's mind, heart and soul.
