The 'Surrender Yourself' model dials up your levels of happiness as you progress from your basic needs (like food and good health) towards your achievements like recognized success, or creative expression. The pinnacle of this human development model is complete surrender.
The 'Fully Human' model is a more subjective way of helping you find your own path. When our most important needs like food, shelter, safety, and stability are met, followed by our need to love, belong and connect with others, we then pursue mastery.
