There’s no pressure like peer pressure.
Shaming the disciplined is an easy way to maintain a sense of normalcy when our standards get challenged by the better choices of others. When I sense that someone’s choice is a statement against my current practice, I have a choice to consider why I choose what I choose or justify my own choices. I can go with the narrative that I am normal and there is nothing wrong with the amount of calories I consume and exercise I avoid. When someone says that they can’t see the movie I just saw because of it’s inappropriate content, I can easily justify my choice because clearly that other person has an immature hang up. It’s more difficult to question why I need the extra calories or the right to see every movie I want to. What benefits could there be in the other choice?
