The happiness which brings enduring worth to life is not the superficial happiness that is dependent on circumstances. It is the happiness and contentment that fills the soul even in the midst of the most distressing of circumstances and most bitter environment. It is the kind of happiness that grins when things go wrong and smiles through the tears. The happiness for which our souls ache is one undisturbed by success or failure, one which will root deeply inside us and give inward relaxation, peace, and contentment, no matter what the surface problems may be. That kind of happiness stands in need on no outward stimulus.
