Foolishness is indeed the sister of wickedness.
A man growing old becomes a child again.
No speech can stain what is noble by nature.
The keenest sorrow is to recognize ourselves as the sole cause of all our adversities.
Hide nothing, for time, which sees all and hears all, exposes all.
There is no success without hardship.
Always desire to learn something useful.
One word frees us of all the weight and pain in life. That word is love.
Old age and the passage of time teach all things.
