“It's a fact—everyone is ignorant in some way or another.

Ignorance is our deepest secret.

And it is one of the scariest things out there, because those of us who are most ignorant are also the ones who often don't know it or don't want to admit it.

Here is a quick test:

If you have never changed your mind about some fundamental tenet of your belief, if you have never questioned the basics, and if you have no wish to do so, then you are likely ignorant.

Before it is too late, go out there and find someone who, in your opinion, believes, assumes, or considers certain things very strongly and very differently from you, and just have a basic honest conversation.

It will do both of you good.”

If one is not careful, one allows diversions to take up one's time—the stuff of life.”

“Anything outside yourself, this you can see and apply your logic to it. But it’s a human trait that when we encounter personal problems, these things most deeply personal are the most difficult to bring out for our logic to scan.
