The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.

Nothing happens to any man that he is not formed by nature to bear.

Despise not death, but welcome it, for nature wills it like all else.

Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

Loss is nothing else but change, and change is Nature's delight.
