At the core, there is one simple, overarching reason why so many people remain unsatisfied in their work and why most organisations fail to draw out the greatest talent, ingenuity, and creativity of their people and never become truly great, enduring organisations. It stems from an incomplete paradigm of who we are - our fundamental view of human nature. The fundamental reality is, human beings are not things needing to be motivated and controlled; they are four-dimensional - body, mind, heart, and spirit.
Stephen CoveyLose/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.
