Hasdai Ibn Shaprut

If one is cruel to himself, how can we expect him to be compassionate with others?

Your son at five is your master, at ten your slave, at fifteen your double, and after that, your friend or your foe, depending on his bringing up.

It is not every calamity that is a curse, and early adversity is often a blessing. Surmounted difficulties not only teach, but hearten us in our future struggles.
