was thinking is called "lateral thinking", coined by UK inventor Edward de Bono. Lateral thinking is important for innovation and creativity in finding a solution. Trump is one of people from this camp of thinking. How do I know it. See this part of interview on Trump many years ago:
Q: What's the last book or article you read that you'd recommend to other entrepreneurs?
A (by Trump): Edward de Bono's Six Thinking Hats thoroughly covers the process of thinking, and it's a way to avoid blind spots if you are thinking alone. He coined the expression "lateral thinking," and this book provides a comprehensive approach to using your brain in an efficient and effective way.
