The man is a success who has lived well, laughed often, and loved much; who has gained the respect of intelligent men and the love of children; who has filled his niche and accomplished his task; who leaves the world better than he found it, whether by an improved poppy, a perfect poem, or a rescued soul; who never lacked appreciation of earth's beauty or failed to express it; who looked for the best in others and gave the best he had.
You must understand the whole of life, not just one little part of it. That is why you must read, that is why you must look at the skies, that is why you must sing and dance, and write poems and suffer and understand, for all that is life.
