You treat the world the way you treat yourself. Any disrespect you have for the world is a reflection of the disrespect you have for yourself. Ken Blanchard speaks of angry people as gray stamp collectors, as opposed to gold stamp collectors. Gold stampers focus on the good and positive things they find in life collecting the good. Gray stampers always qualify the positive.
Gray stampers collect the misery they find in life.
Gunny sackers take each little thing that they perceive about you as something to be used against you. They put it in a gunny sack. When the gunny sack is full they dump it on you. They may bring up things that happened years ago and throw them at you even though they are completely irrelevant now. All grudges are really grudges against yourself.
