Reaction Quotations

A positive attitude causes a chain reaction of positive thoughts, events and outcomes. It is a catalyst and it sparks extraordinary results.
Wade Boggs

Have we not come to such an impasse in the modern world that we must love our enemies - or else? The chain reaction of evil - hate begetting hate, wars producing more wars - must be broken, or else we shall be plunged into the dark abyss of annihilation.
Martin Luther King, Jr.

To every action there is always opposed an equal reaction.
Isaac Newton

Its not stress that kills us, it is our reaction to it.
Hans Selye

We live in a world where finding fault in others seems to be the favorite blood sport. It has long been the basis of political campaign strategy. It is the theme of much television programming across the world. It sells newspapers. Whenever we meet anyone, our first, almost unconscious reaction may be to look for imperfections.
Henry B. Eyring
