David Ogilvy’s timeless principles of creative management
"Kill grimness with laughter. Maintain an atmosphere of informality. Encourage exuberance. Get rid of sad dogs who spread gloom."
Laughter and exuberance are too rarely mentioned in discussions about team building. Informality much underrated in management. We used to get mock complaints from the next door neighbour to our office about the excessive and inappropriate amount of laughter heard throughout the day. She meant, of course, that that was a good - and all too rare - thing.
