Probably the greatest harm done by vast wealth is the harm that we of moderate means do ourselves when we let the vices of envy and hatred enter deep into our own natures.

No man should receive a dollar unless that dollar has been fairly earned.

Nothing in the world is worth having or worth doing unless it means effort, pain, difficulty… I have never in my life envied a human being who led an easy life. I have envied a great many people who led difficult lives and led them well.

Our greatest evils flow from ourselves.

We must seek ways to solve difficulties such as hatred, envy and jealousy.

Envy is more irreconcilable than hatred.
