After four weeks on the New York Times' best seller list with her tell-all autobiography Losing It, Valerie Bertinelli says she's found her true purpose in life. "Every time I hear from someone -- they come up to me and say 'you've inspired me' -- it fills my heart," Valerie says. "They've said they've been inspired, which is exactly what I wanted from this book, that it's very relatable." And those praises are confirming Valerie's own goals: "This is what I want to be here for. I want to be helping people."
