“Bitterness: anger that forgot where it came from.”
“Anger is not bitterness. Bitterness can go on eating at a man's heart and mind forever. Anger spends itself in its own time.”
“Hurt leads to bitterness, bitterness to anger. Travel too far that road and the way is lost.”
“Fits of anger, vexation,and bitterness against ourselves tend to pride and they spring from no other source than self-love, which is disturbed and upset at seeing that it is imperfect.”
“But it always came back to anger.”
“Bitterness is like cancer. It eats upon the host. But anger is like fire. It burns it all clean.”
