When Gilbert's school project challenges him to 'make a difference', grandma introduces him to the mysterious big MAD box. Each of the sides helps Gilbert to focus on a different aspect of the challenge: setting a goal, identifying the reasons behind the goal, developing self-belief, possibility thinking, making a plan and taking action. Finally, Gilbert learns to appreciate what's inside and celebrate his unique qualities and attributes, which have helped him to succeed at his challenge. As grandma tells Gilbert, any problem is really an opportunity in a hat. The story is deliberately split into short chapters, each relating to a step in the thinking process. The resources provided mean readers can plan to make a difference of their own and develop their possibility thinking. Drawing on proven thinking and success strategies used by leading businesses and organisations, this entertaining, accessible and humorous book is designed to show young people the power of having a goal, having a plan and making a difference.
