This practical booklet shows what omdenken means and how to do it. To flip through, to come up with ideas, to be put on the wrong track and especially to trigger your own creative ability. In short, look, think and - particularly - create. It’s not only a Dutch way of life, but every single person, from all over the world, could use a little bit of Omdenken. Take your problem and transform it into a new chance or opportunity. Guided by this booklet. Berthold Gunster (1959) is the founding father of ‘Omdenken’, the Dutch art of flip-thinking. He has written several bestselling books about his ideas. With his team of actors and trainers he performs inspiring shows and workshops in both Dutch and English.
