Confidence has nothing to do with what you look like. If you obsess over that, you'll end up being disappointed in yourself all the time. Instead, high self-esteem comes from how you feel in any moment. So walk into a room acting like you're in charge, and spend your energy on making the people around you happy.
I think fashion is repulsive. The whole idea that someone else can make clothing that is supposed to be in style and make other people look good is ridiculous. It sickens me to think that there is an industry that plays to the low self-esteem of the general public. I would like the fashion industry to collapse.
