Kelly Osbourne claims many people thought she would be dead by now.
The reality TV star has had a well-publicised battle with alcohol and drugs, having been to rehab four times. Earlier this year the 28-year-old also hit the headlines for her drunken breakdown on a flight after reading about the severe symptoms of multiple sclerosis following her brother Jack's diagnosis.
Kelly realises many critics didn't expect her to ever clean up her act, but she is proud of how she has turned her life around.
"Everyone already knows that, deep down, you're meant to be a good person and work hard," she told the latest issue of UK magazine Elle. "There's definitely truth to it - I'm living, breathing proof of that. I mean, who ever thought that I wouldn't be six feet under by now?"
Kelly sought inspiration to follow a new path after reading The Secret by Rhonda Byrne.
The book explains that people can achieve anything they want if they learn to unlock their hidden potential.
Kelly - the daughter of rocker Ozzy Osbourne - says the life-affirming chapters in the tome made her realise she could be happy without being perfect.
"I read this when I was going through a difficult time in my life. Because I was f**ked around so much as a kid, there are some things that I still need to learn," she explained. "I've still got a lot of mistakes to make and this book showed me that you have to make those mistakes in order to grow and to be a better person."
