And no, I'm not talking about "I love you."

The three hardest words for people to say, it seems, is:

"I DON'T KNOW."

For some reason, there's a stigma attached to the idea of letting people know that one doesn't know something.

However, I've found that the more forthcoming we are with what we DON'T know, the more confident those around us are about what we DO know.

Think about it.
