Paulo Coelho - Fear

Fear is a powerful tool. Society uses it to scare us about everything, and to keep us on the track. Family uses it to force to follow their dreams, not our dreams. It took me a long way and I paid a very high price to follow my dream. I'm wondering what to think about Fear, why do people try to instigate this fear in eveybody? And the best option is that, in your opinion, we have, to not respect this unnatural fear and move forward towards our dream.
