To make no mistakes is not in the power of man but from their errors and mistakes the wise and good learn wisdom for the future.

Just as a cautious businessman avoids investing all his capital in one concern, so wisdom would probably admonish us also not to anticipate all our happiness from one quarter alone.

Wisdom allows nothing to be good that will not be so forever no man to be happy but he that needs no other happiness than what he has within himself no man to be great or powerful that is not master of himself.

We don't receive wisdom we must discover it for ourselves after a journey that no one can take for us or spare us.

We give advice, but we cannot give the wisdom to profit by it.
