One can learn to focus on "opportunity" as the gift within every given moment. This attitude towards life always improves the situation. Even in times of sickness, someone who habitually practices grateful living will look for the opportunity that a given moment offers and use it creatively.
David Steindl-RastAny change in attitude changes the way one sees the world, and this in turn changes the way one acts.
David Steindl-RastAmong 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.
