Helen Keller 
Optimism 

‘Most people measure their happiness in terms of physical pleasure and material possession. Could they win some visible goal which they have set on the horizon, how happy they could be! Lacking this gift or that circumstance, they would be miserable. If happiness is to be so measured, I who cannot hear or see have every reason to sit in a corner with folded hands and weep. If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, so thoughtful that it becomes a philosophy of life, —if, in short, I am an optimist, my testimony to the creed of optimism is worth hearing. As sinners stand up in meeting and testify to the goodness of God, so one who is called afflicted may rise up in gladness of conviction and testify to the goodness of life.’—From Helen Keller’s ‘Optimisim.’
