I use to work with and manage some of the smartest people on the planet. However intelligence is really about thinking quickly. I have a high IQ because I think very quickly and therefore can solve problems the same way. However success in one's field is more related in the ability to do scenarios. If you focus on solving a problem you seldom accomplish much. If you focus on the alternatives and redefining the question, you make much more of an impact. All of the times that people that I was intelligent it was because I figured out what the real problem was and not the problem as stated. If you want to be more intelligent, create many scenarios for any situation. Then figure out which one gives the best chance for overall success. When you see a lightbulb, don't think light-Think resistor, heat source, security, injury avoidance system,cullet source, etc,etc, etc,etc, etc
