IMAGINATION

Logic will get you from A to B. Imagination will take you everywhere.
-Albert Einstein

I love this guy. Did you know that he studied on ETH Zurich? I have a firm belief that imagination is one of hallmarks of human being. Thinking outside the box is what drives our quality of life. Imagination is sometimes regarded as a creativity.

Being creative makes your life longer. On the other hand, stress shortens it. It is my firm belief (and scientificly proven fact) that creative people are less affected to stressors. They tend to see them as challenges rather than hurdles impossible to overcome. You can read more in the Scientific American.

            Dr. Leo Esaki, the Nobel Laureate, indicated that the most creative period in human life is exactly the age I am (20-30 years old). He had shown that the most of innovation and discoveries by other Nobel Laureates were made at the average age of 32 (but Nobel prize itself was awarded even 10-20 years afterwards). More about that fact is here.
