I was lucky enough to go the Howies Little Big Voice lectures last year. It was a completely excellent thing. Great talking, splendid people and a fantastic location. They're doing something similar this September, they're calling it the Do Lectures and they're offering free places to people who write them a convincing and imaginative letter. If you're looking for inspiration about things to Do to change the way you work, or consume, or make, or live it'd be a great place to start. More information here.
