“Happiness is beneficial for the body but it is grief that develops the powers of the mind.”

“Happiness lies in dedicating oneself to an idea, the fruits of which are beneficial for others.”

“Work is a wonderful regulator of mind and body. I forget all sorrow, grief, bitterness, and I even ignore them altogether in the joy of working.”

“There is no greater grief than to find no happiness, but happiness in what is past.”

“A sound mind in a sound body, is a short but full description of a happy state in this world.”

“In short, if your body or mind
Or your soul or your purse come to grief,
You need only get drunk, and you'll find
Complete and immediate relief.”

“Physical fitness is the first requisite of happiness. Our interpretation of physical fitness is the attainment and maintenance of a uniformly developed body with a sound mind fully capable of naturally, easily, and satisfactorily performing our many and varied daily tasks with spontaneous zest and pleasure.”

“All our power lies in both mind and body; we employ the mind to rule, the body rather to serve; the one we have in common with the Gods, the other with the brutes.”
Sed nostra omnis vis in animo et corpore sita est; animi imperio, corporis servitio magis utimur; alterum nobis cum dis, alterum cum beluis commune est.

“Minds vary in sensitiveness and in self-power, as bodies do in susceptibility of attraction and repulsion.”

“Our happiness depends on the habit of mind we cultivate. So practice happy thinking every day. Cultivate the merry heart, develop the happiness habit, and life will become a continual feast." ~”
