At Lean Mean Fighting Machine we think that the more fun you have at work, the better the work becomes. We’re doing a talk at Cannes around this very theme, and would like you to help out. Do you agree with us? What evidence, theories, anecdotes or hearsay is there to show that having fun is the best way to achieve great things. Not just in advertising you understand, but in industry, the arts and life itself. The best posts will get featured in the show.
