   Coming from different cultures and having different backgrounds, inventors do not seem to have much  3.  common.  But creative thinking,   4.  is greatly valued, is perhaps the basic skill an inventor should have. In order to explore new possibilities, you will have to learn to break 5.     from old thought patterns. When you get stuck, try to look at the problem in        6.     many ways as possible. Each new way may improve your understanding.
