No one can have all he desires.

The wise man will always reflect concerning the quality not the quantity of life.

A good conscience fears no witness, but a guilty conscience is solicitous even in solitude. If we do nothing but what is honest, let all the world know it. But if otherwise, what does it signify to have nobody else know it, so long as I know it myself? Miserable is he who slights that witness.

No man is nobler born than another, unless he is born with better abilities and a more amiable disposition. They who make such a parade with their family pictures and pedigrees, are, properly speaking, rather to be called noted or notorious than noble persons.
