"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" said Kangana at the launch of journalist Barkha Dutt's book, "The Unquiet India" here.
"So I've been through struggle for 10 years, and I think that's what shaped me up as a person today. I don't know how much a success people see me as - that is very external aspect of one's growth - but I think I'm a very successful person on a very personal level. And when you lose something or face failure, it's about how you deal with it and not lose your self-respect and self-worth," 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.
Kangana, who was aspiring to be a doctor before she decided to enter the film industry, says that right from schools, the system of success or 'standing first in class' is prominent. She also faced trauma due to her parents' strange behavior if she didn't stand first in class.
"We need to tell our children that it is okay to fail, there's nothing wrong in it. Nothing lasts forever. That kind of spirit needs to be there," she said.
Kangana also feels that this kind of prominence given to success and winning, creates a feeling where a rejection is hard for people to accept. She believes that's the reason violence against women happen, having seen her sister Rangoli suffering an acid attack.
"So rejection is so hard to deal with for anyone, especially men, there's no acceptance for the fact that this women doesn't want or that she doesn't have feelings for me. Usually that is the intention and I feel that for 90 per cent of the violence against women - that kind of rejection triggers it."
Kangana also confessed about being physically abused by an industry celebrity and how she is fighting back physically and legally.
