Charles Darwin began as an underachieving schoolboy, Leonardo da Vinci as an illegitimate outcast. The secret of their eventual greatness lies in a 'rigorous apprenticeship': by paying close and careful attention, they learnt to master the 'hidden codes' which determine ultimate success or failure. Then, they rewrote the rules as a reflection of their own individuality, blasting previous patterns of achievement open from within. Told through Robert Greene's signature blend of historical anecdote and psychological insight and drawing on interviews with world leaders, Mastery builds on the strategies outlined in The 48 Laws of Power to provide a practical guide to greatness - and how to start living by your own rules.
