You hit what you aim at, and if you aim at nothing you will hit it every time.
Life is an echo. What you send out comes back. What you sow you reap. What you give you get. What you see in others exists in you.
What a mistake to suppose that the passions are strongest in youth. The passions are not stronger, but the control over them is weaker. They are more easily excited; they are more violent and apparent, but they have less energy, less durability, less intense and concentrated power than in mature life.
