"Life is made up of little things. He who travels over a continent must go step by step. He who writes a book must do it sentence by sentence; he who learns a science must master it fact by fact, and principle after principle. What is the happiness of our life made up of? Little courtesies, little kindnesses, pleasant words, genial smiles, a friendly letter, good wishes, and good deeds. One in a million, once in a life-time, may do a heroic action. But the little things that make up our life come every day and every hour."
