Helen Keller said this quote
“ Certainly I believe that God gave us life for happiness, not misery. Humanity, I am sure, will never be made lazy or indifferent by an excess of happiness. Many persons have a wrong idea of what constitutes true happiness. It is not attained through self-gratification but through fidelity to a worthy purpose. Happiness should be a means of accomplishment, like health, not an end in itself. ”
