To keep the body in good health is a duty... otherwise we shall not be able to keep our mind strong and clear.
Buddha

Epictetus

Keep your face always toward the sunshine - and shadows will fall behind you.
Walt Whitman

Remember when life's path is steep to keep your mind even.
Horace

The walls we build around us to keep sadness out also keeps out the joy.

In dwelling, live close to the ground. In thinking, keep to the simple. In conflict, be fair and generous. In governing, don't try to control. In work, do what you enjoy. In family life, be completely present.
Lao Tzu
