'When you have a lemon, make a lemonade.' That is what a great educator does. But the fool does the exact opposite. If he finds that life has handed him a lemon, he gives up and says, 'I 'm beaten. It is fate. I haven't got a chance.' Then he proceeds to rail against the world and indulge in an orgy of self-pity .
