Do you ever wonder why instead of doing things you just sit and look out at things? Normally it's fear. Fear tells you that you shouldn't do something...that you'll make a fool of yourself, hurt yourself, lose money, etc. But fear is lame. Fear has lived in it's parent's basement for the last 2 million years. Fear has no friends and is never invited to parties. So let fear sit alone...you don't want to keep it company.
