Be careful to leave your sons well instructed rather than rich, for the hopes of the instructed are better than the wealth of the ignorant.
Other quotes by Epictetus
To accuse others for one's own misfortunes is a sign of want of education. To accuse oneself shows that one's education has begun. To accuse neither oneself nor others shows that one's education is complete.
No greater thing is created suddenly, any more than a bunch of grapes or a fig. If you tell me that you desire a fig, I answer you that there must be time. Let it first blossom, then bear fruit, then ripen.
