Why is it that we often do not do what we really would like to do? Where does that inner voice come from that stops us from living life to the full?Yes, but …I cannot do that …I am too old for that …that is the way I am …what will that cost me …not nowYes-but as an attitude towards life can hardly be called fruitful. It makes us careful, sceptical and suspicious. After all, thinking about life is something different from partaking in it. If we are not careful, we will weigh up the pros and cons so long that all opportunities will have passed us by and we will have become bystanders of our own life.But there is hope. There is another attitude towards life: yes-and. In the world of yes-and there are no frontiers. Everything is possible. It is the attitude of inspirational thinkers, leaders with a global vision and exceptional artists. It seems that ‘what they do’ coincides effortlessly with ‘who they are’.The aim of this book is to change yes-but behaviour into yes-and behaviour. In ten rules Berthold Gunster explains how to make that change. ‘Yes, but’ will never sound the same again.
