Peter Drucker is an icon of the business world. The methods developed by this genius were so powerful that they are still used today in organizations all over the world. Yet one of his most important contributions is still little known. Drucker had uncovered principles of self-development that he put into practice himself – principles that enabled him to reach all of his life goals. For the first time, this book examines the self-development methods that Drucker created and practiced – and offers vital and original lessons to anyone in business on how to accomplish any goal in any endeavour. For as Drucker wrote: “The most crucial and vital resource you have as an executive and as a manager is yourself; your organization is not going to do better than you do yourself.”
