So what gets in the way of our pursuit of it? I think we most often resist going through the process of mastery for two reasons: it can be deeply uncomfortable along the way and we doubt our ability to become expert.
I think that this statement is 100% true. When people first start to get into new things and new skills then it probably seems very weird at first. For example if it's a sport then you're not going to be used to it after. It may feel uncomfortable because it's something that is new for you and your body/mind has to get the chance to adapt to it. As time goes on you gradually start getting better and better at this skill and it becomes a hobby or like the title states...something you're really good at.
