Actress Kangana Ranaut intends to write a book on all the struggles she has faced in her life, including the time before she came to the film industry as well as after. “The way I dealt with my failures has been very heavy and I would like to write a book about that, how success will never teach you anything,” Ranaut said at journalist Barkha Dutt's book launch. “So I've been through struggle for 10 years, and I think that's what shaped me up as a person today,” she said. “Ten years of humiliation, rejection, embarrassment could've made me believe what the whole world thought about me - like if they thought about me as a loser, but I didn't think of myself as that or as what the world or my parents thought of me. That's why I could do what I did in my life... Not just in India but all over the world, winning and success in so overrated,” she added.
