Book excerpt: For the first time, music legend and humanitarian activist Dionne Warwick reflects on 50 years in showbusiness and the lessons she has learned from being an artist, a mother and a global icon. From her rise to superstardom to raising millions of dollars for AIDS research, she gives readers a glimpse into her dazzling, inspiring life. 'If you think you can do it, you can do it' was the advice she got from her grandfather as a young girl - words she has never forgotten. Like her music and humanitarian work, her story is guaranteed to give hope and inspiration to people across the world.
