As a child, you were gifted with imagination and creativity. Now grown up, you base your judgment on your knowledge and experience. How to think like a child?
"We have been constructed by schools and parents in such a way that for all problems we have a formula we can apply. This is what society provides us with in order to be efficient and independent.
Nine times out of ten, this is what gets us out of complicated situations.
But once in a while,if you could think differently, you might find some other solutions, easier and more effective."
