Johann Georg von Zimmermann

Many have been ruined by their fortunes, and many have escaped ruin by the want of fortune. To obtain it the great have become little, and the little great.

Open your mouth and purse cautiously; and your stock of wealth and reputation shall, at least in repute, be great.

Never lose sight of this important truth, that no one can be truly great until he has gained a knowledge of himself, a knowledge which can only be acquired by occasional retirement.

Be not so bigoted to any custom as to worship it at the expense of truth.

Never suffer the prejudice of the eye to determine the heart.

Open your mouth and purse cautiously, and your stock of wealth and reputation shall, at least in repute, be great.
