"Attention is of the essence of our powers; it is that which draws other things towards us, it is that which, if we have lived with it, brings the experience of our lives ready to our hand. If things but make impression enough on you, you will not forget them; and thus, as you go through life, your store of experiences becomes greater, richer, more and more available. But to this end you must cultivate attention - the art of seeing, the art of listening. You needn't trouble about memory, that will take care of itself; but you must learn to live in the true sense. To pay attention is to live, and to live is to pay attention..."
