It is the nature of people and characters as well, to try and find a source of joy and a resolution to that which hurts them. This hurt might be physical suffering or mental torment. The resolution may be to rearrange one’s environment or to come to terms with the environment as it is. Regardless of the source of the inequity or the means employed to resolve it, all thinking creatures try to maximize their pleasure and minimize their pain. That is the primal force which drives us in our lives, and the dramatic force that drives a story.
If our environments would instantly respond to our desires and if our feelings would immediately adjust to new attitudes, all inequities between ourselves and our environments would be equalized at once. Unfortunately, this is not the case. Rather, to solve external problems we must apply effort to rearrange the material that surrounds us, and to solve internal problems we must adopt a series of paradigm shifts to arrive at a perspective that minimizes our anguish.
