Billions of people know how to drive cars. but there is only a small fraction of these people who know how to build a car. And even fewer who can make a complete on their own. Knowing how to drive a car is not the same thing as knowing how to make a car or how a car works. It does not matter.

I do not need to know who or what I am to know how to live. Just live. Knowing some things may help but mostly it may not be necessary.

It is our ability to decide what is and what is not necessary knowledge that counts.
