Answer 2

Despite being physically challenged, Helen Keller lived a quality life which even most of the normal people fail to live.
Even as a child, she was very sharp, inquisitive, eager and self-asserting. just at six months she could utter incomplete sentences such as "How d'ye" and words like "Tea, tea, tea" quite plainly. She took her first step when she was just a year old. Having enjoyed a normal life for 19 months, Helen was attacked by a mysterious illness that robbed her of her sight and her sense of hearing. This changed the course of her life.
Right from her childhood she was full of life. Whether playing with Martha, snipping off locks of her hair or playing pranks on her mother and teacher when she locked them up., Helen showed them thee urge to keep herself occupied and have fun in life. She liked to explore the world around her and whatever opportunity life offered her she grabbed them with both her hands and made the best of them. Initially due to her failures she was a sullen, angry child, who very often resorted to outburst of passion, but once Miss Sullivan started to teach her, her anger cooled down, and her inner peace and beauty stared to bloom. Her patience, strong willpower, determination and perseverance helped her conquer her handicaps and learn to communicate with others, thus breaking the barriers of the dark and silence around her. 
Despite her deprivations, Helen neither indulged in any self pity nor lost her self-confidence. Like normal human beings, this physically challenged great woman kept on aspiring to achieve higher and higher goals in life. However, even when she attained great heights of success, she never turned her head. In fact she gave all the credit of her accomplishment to her friends, her teacher and her family. She never lost interest in life and remained alive to the world around her. She lived life to the full and proved to be a source of inspiration to her fellow beings.
