A teenage snooker prodigy, Ronnie O'Sullivan turned professional with the highest of expectations. This pressure, together with a challenging personal life, catapulted Ronnie into a life of excess and addiction. Whilst he appeared at the height of the game to spectators, these were the moments when he felt at his lowest. In 2000 he 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, but success has now taken on a new meaning for the world champion. Framed around twelve lessons Ronnie has learned from his extraordinary career, with this book he takes us beyond the success and record-breaking achievements to share the reality - and brutality - of what it takes to rise to the very top, whatever your field.
