Ralph Waldo Emerson said that..

TO LAUGH OFTEN AND MUCH; TO WIN THE RESPECT OF INTELLIGENT PEOPLE AND THE AFFECTION OF CHILDREN; TO EARN THE APPRECIATION OF HONEST CRITICS AND TO ENDURE THE BETRAYAL OF FALSE FRIENDS. TO APPRECIATE BEAUTY; TO FIND THE BEST IN OTHERS; TO LEAVE THE WORLD A BIT BETTER WHETHER BY A HEALTHY CHILD, A GARDEN PATCH, OR A REDEEMED SOCIAL CONDITION; TO KNOW THAT EVEN ONE LIFE HAS BREATHED EASIER BECAUSE YOU HAVE LIVED. THIS IS TO HAVE SUCCEEDED.
