2) My Left Foot - By Christy Brown
My Left Foot is the autobiography of Christy Brown, an man born with Cerebral Palsy in early 1930's Ireland.
In the introduction, Brown writes about his life as a young boy growing up in Dublin. As a baby, his mother noticed that he could not hold his head up on his own. Later on he was diagnosed as having Cerebral Palsy, and everyone assumed he was physically and mentally handicapped. Everyone in his family thought he was a waste, but his mother who didn't give up on him.
One day while his little sister was playing with a piece of chalk, he took hold of it using the only part of his body he could control - his left foot and drew a scribble that resembled the letter 'A'. From then, everyone realised he wasn't mentally handicapped.
Christy went on to be a Painter, Writer and Influencer later in life and his autobiography basically tells you how it happened.
