How would your life be different if you were incapable of feeling fear? Would your life be better or worse than it is now?
I am not altogether sure that I want a life without fear. I am so perfectly happy with where I am at in my life right now and I know that my fears have contributed to to who I am today and where I have been.
Fear is an instinct that is triggered to tell us when danger is nearby. Sometimes our fears are silly like being afraid of the dark, but sometimes our fears are real, such as being afraid of a person who could hurt you.
Our fears help shape our lives. Sometimes they hold us back, but sometimes they save us. It is hard to say whether or not my life would be better or worse without fear because that is asking how different would your life be if you made choice A over choice B. You just cannot know the answer.
