People tell me that I just have to do it and it gets easier over time. Play that role that you want to play and soon you'll get more comfortable being that person. These steps feel too big for me, though. It's like learning to juggle. You don't just start throwing three balls around. The first step is getting comfortable with that single ball before you add the second and third.
But I keep on trying to throw all three balls in the air and just end up dropping everything and embarrassing myself.
