I was reading Barbara's blog (http://penonfire.blogspot.com/) and in today's entry, she mentions a quote she heard Bobby Flay (Food Network) say on his show. "If you're not nervous about your passion, you're not passionate about it."
In a sense, I've been told this all my life in one form or another. I've always been told that if you don't fear doing something, it doesn't mean anything to you. You can look at that in so many possible ways. Think about all of the really big fights you've had with people in your life. The intensity of the emotions show you how important each thing or person was or is to you. When you stop fighting, you stop caring. To this I say; Never stop fighting. Never give up. Follow your passion. Give meaning to your life. Never give up.
