The earth is given as a common for men to labor and live in.

Cultivators of the earth are the most valuable citizens. They are the most vigorous, the most independant, the most virtuous, and they are tied to their country and wedded to it’s liberty and interests by the most lasting bands

The earth belongs to the living, not to the dead.

No occupation is so delightful to me as the culture of the earth, and no culture comparable to that of the garden.

Nothing can stop the man with the right mental attitude from achieving his goal; nothing on earth can help the man with the wrong mental attitude.

We are, perhaps, uniquely among the earth's creatures, the worrying animal. We worry away our lives, fearing the future, discontent with the present, unable to take in the idea of dying, unable to sit still.
