The story of the human being and the human psyche has been examined, studied, and written about since the beginning of our existence. Although it's been researched and dissected by brilliant thinkers, explored and explained by the greatest intellects of all time, most of us are still living in the dark, perplexed by the behavior of our friends, our family members, our idols, and—more often than not—ourselves. Disappointed by the condition of our own lives, we forge ahead each day hoping that our darker impulses and bad behaviors will miraculously disappear.

Hurt time and again by the flaws that we can't seem to shake free of, we silently pray that we will find the courage to give up our procrastination, our overspending, our chocolate, our resentments, or our sharp tongues. Yet we continue to succumb to our lower impulses, sabotage our own desires, and neglect our future. In an attempt to hide our discontent, we put on a happy face, muster our best "everything is fine" look, and continue acting out in ways that undermine our self-esteem and defeat our best-laid plans.
