Why, human thought is a real element, a real force, darting out like electricity from every man's or woman's mind, injuring or relieving, killing or curing, building fortunes or tearing them down, working for good or ill, every moment, night or day, asleep or awake, carving, moulding and shaping people's faces and making them ugly or agreeable.

Look forward. Every regret, every mournful thought, takes so much out of your life.

Goodwill to others ... helps build you up. It is good for your body. It makes your blood purer your muscles stronger and your whole form more symmetrical in shape. It is the real elixir of life.
