There are no greater wretches in the world than many of those whom people in general take to be happy.

Humanity is fortunate, because no man is unhappy except by his own fault.

It is the failing of youth not to be able to restrain its own violence.

Every one has time if he likes. Business runs after nobody: people cling to it of their own free will and think that to be busy is a proof of happiness.

There is no benefit so large that malignity will not lessen it; none so narrow that a good interpretation will not enlarge it.

In the meantime, cling tooth and nail to the following rule: not to give in to adversity, not to trust prosperity, and always take full note of fortune's habit of behaving just as she pleases.

People pay the doctor for his trouble; for his kindness they still remain in his debt.
