"Lose/Win people bury a lot of feelings. And unexpressed feelings come forth later in uglier ways. Psychosomatic illnesses often are the reincarnation of cumulative resentment, deep disappointment and disillusionment repressed by the Lose/Win mentality. Disproportionate rage or anger, overreaction to minor provocation, and cynicism are other embodiments of suppressed emotion. People who are constantly repressing, not transcending feelings toward a higher meaning find that it affects the quality of their relationships with others."
