Bollywood king Shah Rukh Khan will soon release his autobiography titled "Twenty Years in a Decade", reported Press Trust of India. The actor said his book is nearing completion but did not cite its release date. He said he will soon pen down the last chapter on Kolkata, where he describes his love for the place.

"I keep writing. The chapter that I haven't written yet is on Kolkata. While working very hard on "Jab Tak Hai Jaan", I got no time, but I will start writing", Shah Rukh told the news agency. "I don't want anything to be left out of which I have lovely memories," he added. Shah Rukh made the announcement of his autobiography at the 18th Kolkata International Festival held over the weekend.

The book talks of his journey from being a simple Delhi boy to successful stardom. He started his career with television shows "Fauji" and "Circus". It was only after the release of his debut film "Deewana" in 1992, when Shah Rukh gained recognition.

Since then there was no looking back for the superstar. Despite leaving a permanent mark in the film industry, the actor is apparently worried of being a failure just as his father was. "I think my father was most successful failure in the world and I am proud of him," he said.

"I have a beautiful family. I have a few friends with whom I spend lot of time. I don't want to die like my father. I don't want to be unknown. I would like to be just successful. Believe me it is lonely at the top", he confessed. Shah Rukh's father, Taj Mohammed Khan, died from cancer when the actor was 15. His mother, Lateef Fatima, passed away in 1990. His older sister Shahnaaz is rarely seen in the public eye.
