Say 'I don't know.' It's a doorway, not a weakness.

Many of us are afraid to say "I don't know." We fear looking foolish, unqualified, behind.

But "I don't know" is one of the most honest and powerful things a person can say. It opens the door to learning. It invites others in. It makes room for better answers than the one you'd have faked.

The people who never admit it stay stuck in small rooms.

Walk through the doorway. There's a whole library on the other side.
