Among the many things that profoundly impress me about the Dalai Lama, quite high up on the list is his ability to say "I don't know". I've often wished that other people in prominent positions wouldn't feel the compulsion to have an answer for everything and would feel equally free to say "I don't know." It's a sign of wisdom to know that you don't know and a sign of stupidity to think that you know everything. I admire it enormously in him, and wonder why so few people in leading positions reach that stage.
