 Hi, I'm Johnny Erickson Tata, and a few months ago at a conference, I met three-year-old Hannah, who has spina bifida and uses a wheelchair. When I wheeled up to her, this little girl looked up at me with such admiration and big, doleful eyes, and it occurred to me that this child probably did not know many women in wheelchairs. She probably didn't have many adult role models, but I could be her role model. I was in a wheelchair. I know what it's like.
