Head to any monument in Europe and you will be asked to purchase a selfie stick almost instantaneously.
Walk around for another minute and you will be approached by a beggar with a few coins clanging around in an empty McDonald's cup.
Why are you afraid?
If you fail at what you are pursuing, worst case scenario is that you peddle selfie sticks or shake cups in people's faces for hours on end.
Chances are that won't happen to you.
But if you can come to terms with your worst nightmare, taking risks to do something great becomes less intimidating.
