Fright or Flight

If the early man wasn't afraid of the dark, he wouldn't have created light, if Willbur and Orville Wright didn't step out of their confort zone and created the first aircraft, we would have planes now. Fear and stepping outside of your confort zone is the foundation for everything we have now, because fear motivates us to do things we need to do and stepping outside of our confort zone helps us find new discoveries.
