But how would that help with "facing your fears"?
Good question. I'm no good at getting out of my comfort zone so not much help. I will say that in a way, fear is beneficial as it means that situations are rarely as bad as you expect. It's like in marketing where promising the world is a bad idea as it may be hard to reach this level meaning your customers are always disappointed. So instead you always promise below what you can deliver and then exceed your customers expectations (for instance throw in a 'free' gift when a customer buys something). So when you get worked up and scared about something you'll often find that the situation is better than you thought (i.e. it exceeds your expectations). If you think like this then fear is beneficial.
