What is your instinctive approach to decision making? If you're naturally optimistic, then chances are you don't always consider potential downsides. Similarly, if you're very cautious or have a risk-averse outlook, you might not focus on opportunities that could open up.
Often, the best decisions come from changing the way that you think about problems, and examining them from different viewpoints.
"Six Thinking Hats" can help you to look at problems from different perspectives, but one at a time, to avoid confusion from too many angles crowding your thinking.
