“Love all, trust a few,
Do wrong to none: be able for thine enemy
Rather in power than use; and keep thy friend
Under thy own life's key: be check'd for silence,
But never tax'd for speech.”
― William Shakespeare, All's Well That Ends Well

“Love is that condition in which the happiness of another person is essential to your own.”
― Robert A. Heinlein, Stranger in a Strange Land

“For every minute you are angry you lose sixty seconds of happiness.”
― Ralph Waldo Emerson

“Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.”
― Martin Luther King Jr., A Testament of Hope: The Essential Writings and Speeches
