"When the deepest part of you becomes engaged in what you are doing, when your activities and actions become gratifying and purposeful, when what you do serves both yourself and others, when you do not tire within but seek the sweet satisfaction of your life and your work, you are doing what you were meant to be doing. The personality that is engaged in the work of its soul is buoyant. It is not burdened with negativity. It does not fear. It experiences purposefulness and meaning. It delights in its work and in others. It is fulfilled and fulfilling."
-Gary Zukav, The Seat of the Soul
