We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale -- identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual.

"Life is an opportunity, benefit from it. Life is a beauty, admire it. Life is a dream, realize it. Life is a challenge, meet it. Life is a duty, complete it. Life is a game, play it. Life is a promise, fulfill it. Life is sorrow, overcome it. Life is a song, sing it. Life is a struggle, accept it. Life is a tragedy, confront it. Life is an adventure, dare it. Life is luck, make it. Life is life, fight for it."
