Mark Dando & Doug Richardson are co-founders of Coloured Square Ltd. Since 1998, they've evolved their unique approach to learning and development via their simple but powerful Coloured Square Universal Toolkit(TM). They've provoked thousands of people in many big-name organisations to change the way they think and behave, in order to be more effective and get more of what they want in their work and in their lives. They are specialists in noticing and challenging the mindsets which people are currently using - the mindsets which affect their ability to adopt new behaviours. Mark lives in Bristol. Doug lives in Nottingham. This is their second book. They both love the work they do. To find out more, visit the Coloured Square website at www.colouredsquare.com.
