Mukesh Ambani is one of the richest men in the world and his rise to billionaire status is the stuff fairy tales are made of . But how did the man who has everything grow up? Well, imagine being squeezed into a one-room flat with nine people. Or how about getting sent to the garage as a kid as punishment? Behind the mansions, the private security and the spectacle of being an Ambani is the story of a self-confessed shy man who just wanted to make his dad proud. In his first interview on Rendezvous with Simi Garewal in 2012, posted on YouTube, Mukesh opened up about his life before being ultra-rich.

He credits his father for his success and says he has always remained focused on achieving the end game.

The billionaire recounts how he and his brother/rival Anil once got punished after misbehaving as young boys. The family had guests over and the two brothers ate the food prepared for the visitors and jumped on the sofa. While his dad laughed it off in the moment, the next day he banished them to the garage with nothing but water and roti, and said they had to repent. Mukesh was 10 at the time. He said they learned their lesson and were never naughty when guests were over again.

The father and son enjoyed a close relationship and, with tears in his eyes, Mukesh explains how he witnessed his father’s first stroke. They were watching cricket on February 16, 1986, when Dhirubhai told his son that his back was hurting. Suddenly he fell unconscious and was rushed to hospital. Doctors told the family that the next 24 hours would be critical. When Dhirubhai did wake up, instead of asking where he was and what had happened, he told Mukesh, “Don’t worry, I will make it.” Mukesh says the fact that his dad was more concerned about reassuring him than what had happened spoke volumes about the type of person he was. In 2002, Dhirubhai suffered his second stroke and passed away, leaving a hole in the Ambani family. Want more stories like this? Sign up here.
