Every year I gather 20+ MBA students together and many of them think they're NOT creative. Somehow they have the idea that it's all about flower arranging, strutting around in a tutu and composing symphonies.
Wikipedia defines it thus:
'Creativity refers to the phenomenon whereby something new is created which has some kind of value.'
We then find out who they are. Some are parents who face new challenges daily and find ways to overcome them without reading a baby manual. Some are motorcyclists or mountaineers and have worked their way out of tricky problems miles from any other human being, improvising with whatever materials they have to hand.
All of them work in organisations that have internal politics, competition, external threats and various levels of chaotic management. They've all navigated their way through the rapids and waterfalls to arrive on the course.
I conclude that they are all creative, but most of them don't recognise it...
