It is not to taste sweet things; but to do noble and true things, and vindicate himself under God's heaven as a God-made man, that the poorest son of Adam dimly longs. Show him the way of doing that, the dullest day-drudge kindles into a hero. They wrong man greatly who say he is to be seduced by ease. Difficulty, abnegation, martyrdom, death, are the allurements that act on the heart of man. Kindle the inner genial life of him, you have a flame that burns up all lower considerations.
Thomas CarlyleA man's felicity consists not in the outward and visible blessing of fortune, but in the inward and unseen perfections and riches of the mind.
Thomas Carlyle
