In a career spanning over three decades, Ronnie O'Sullivan's journey to becoming the greatest snooker player of all time has been filled with extremes.A teenage snooker prodigy, Ronnie turned professional with the highest of expectations. This pressure, together with a challenging personal life, catapulted Ronnie into a life of excess and addiction. He was winning titles - his first within a year of turning professional - but losing himself and his game as he tried to block out the mental pain and misery. Whilst Ronnie appeared at the height of the game to spectators, these were the moments when he felt at his lowest.In the year 2000 Ronnie started rehab and began the journey to get his life back, addressing his demons and working on developing a stronger and more resilient mindset. More than twenty years on, Ronnie is still obsessed with delivering his peak performance and never happier than when in a snooker hall, but success has now taken on a new meaning for the record-equalling world champion.
