The best doctor gives the least medicines.

If you can't pay for a thing, don't buy it. If you can't get paid for it, don't sell it.

The best of all medicines is resting and fasting

[T]he more public provisions were made for the poor, the less they provided for themselves, and of course became poorer . . . [taking] away from before their eyes the greatest of all inducements to industry, frugality, and sobriety, by giving them a dependence of somewhat else than a careful accumulation during youth and health for support in age and sickness.

Do not fear mistakes.

Nature performs the cure, the physician takes the fee.

He that goes a borrowing goes a sorrowing.
