AnswersWell, they say that daydreaming makes you more creative. I remember one time I had been trying to work out the details of a presentation.I'd got stuck trying to connect two distinct parts in the final section and needed a way of bringing them together. I'd been racking my brains for about a week and nothing had worked. Then I was travelling home by train and had started reading the paper but actually was just staring out of the window, daydreaming and sort of allowing my mind to freewheel. Suddenly there it was, the answer I had been looking for. It just popped into my head from nowhere. The perfect solution.
