I love this question. I believe that people are scared. Scared of failure. But why should fear of failure this stop you from fulfilling your dreams.
When achieving your goals and fulfilling dreams: Yes you will be judged (use these people to drive you), yes you will have to jump over obstacles and push through hard times, and yes, it will take a lot of hard work and effort, everyday.
However, If you have a dream, and only one life. Failure should not scare you, but force you.
I believe there is no such thing as failure, you may have a drawback. However if you can keep on going and learn from your mistakes, you will most likely find yourself in bigger and better places.
Be willing. Learn from mistakes. Push yourself.
