The fool learns by suffering.
The man who is rich in fancy thinks that his wagon is already built; poor fool, he does not know that there are a hundred timbers to a wagon.
There is also an evil report; light, indeed, and easy to raise, but difficult to carry, and still more difficult to get rid of.
Only fools need suffer to learn.
A day is sometimes our mother, sometimes our stepmother.
Often even a whole city suffers for a bad man who sins and contrives presumptuous deeds.
