I needn't tell you that success and failure prove nothing - the whole thing is a lottery. It's pleasant to succeed; but for a philosophic mind it oughtn't to be very upsetting to fail.
George SandAll your trouble comes from lack of exercise. A man of your strength and constitution ought always to have kept physically active. So don't jibe at the very wise advice that sentences you to one hour's walk a day. You imagine the work of the mind takes place only in the brain; but you're much mistaken. It takes place in the legs as well.
George Sand
