Even happiness itself may become habitual. There is a habit of looking at the bright side of things, and also of looking at the dark side. Dr. Johnson has said that the habit of looking at the best side of a thing is worth more to a man than a thousand pounds a year. And we possess the power, to a great extent, of so exercising the will as to direct the thoughts upon objects calculated to yield happiness and improvement rather than their opposites.
Samuel SmilesThe women of the poorer classes make sacrifices, and run risks, and bear privations, and exercise patience and kindness to a degree that the world never knows of, and would scarcely believe even if it did know.
