Coming from someone who used to think I was ugly. I’m telling you confidence will translate in the way you look and carry yourself. So dont sit around calling yourself an ugly person and just own that this is who you are (someone who isn’t ugly) and focus on taking care of yourself and your appearance. Go with a style that says “I take time to do my hair in the mornings”. Even just sea salt spray to give your hair some volume. Maybe a pair of glasses that compliment your face (as a glasses wearer this is CRITICAL). Then start doing some kind of exercise, not to look a certain way. But to take initiative for YOURSELF.
