A man will fight harder for his interests than for his rights.
-Napoleon Bonaparte
It is impossible to suffer without making someone pay for it; every complaint already contains revenge.
-Friedrich Nietzsche
Do not take this material world so seriously because it is always changing. Something terrible that you take so seriously today is going to change tomorrow.
By degrees, little by little, from time to time, a wise person should remove his own impurities as a smith removes the dross from silver.
