Phillips Brooks, the author of the famous hymn “O Little Town of Bethlehem.” He wrote: Sad will be the day for every man when he becomes absolutely contented with the life he is living, with the thoughts that he is thinking, with the deeds that he is doing, when there is not forever beating at the doors of his soul some great desire to do something larger, which he knows that he was meant and made to do.
