He's the best physician that knows the worthlessness of most medicines.
At a great pennyworth pause a while.
A lonely man on a rainy night who cannot read.
Diligence overcomes difficulties; sloth makes them.
Singularity in the right hath ruined many; happy those who are convinced of the general opinion.
La pereza anda tan despacio que la pobreza no tarda en alcanzarla.
