That a man be willing, when others are so too, as far forth as for peace and defense of himself he shall think it necessary, to lay down this right to all things; and be contented with so much liberty against other men, as he would allow other men against himself.
To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
You might as well expect rivers to run backwards as any man born free to be contented penned up.
Watch your manner of speech if you wish to develop a peaceful state of mind. Start each day by affirming peaceful, contented and happy attitudes and your days will tend to be pleasant and successful.
