Scott Steinberg's productive fear speech gets to the heart of the two different kinds of fear and provides road maps for reacting to both.
Steinberg starts off by dividing fear into two different categories: anxiety and fear of being outside your comfort zone. He defines anxiety by being scared of fear itself. This kind of fear can often lead to paralysis because we simply don't move in any direction. We're locked in place and make no moves as the world around us goes on. This is the worst kind of fear according to Steinberg, especially in terms of business innovation.
Fear of being outside your comfort zone is a good kind of fear according to Steinberg. It means you're attempting to adapt and do something new to keep pace with an ever-changing world.
