In health there is freedom. Health is the first of all liberties.

There is no curing a sick man who believes himself in health

Health is the first of all liberties, and happiness gives us the energy which is the basis of health.

Conquering any difficulty always gives one a secret joy, for it means pushing back a boundary-line and adding to one's liberty.

He who asks of life nothing but the improvement of his own nature... is less liable than anyone else to miss and waste life.

Tell me what you feel in your room when the full moon is shining in upon you and your lamp is dying out, and I will tell you how old you are, and I shall know if you are happy.
