This I kid you not. How you look matters. More than for other people, it is for you. Yes, yourself. When you have made an effort on your personal appearance, you will feel good. You will feel confident. And that is where you shine. You can be brilliant. That is good too. But it is nothing quite like it when you feel good about yourself because you made an effort on how you look. When you do that, you know for a fact that you look great and that is all you need. You do not need approval from other people and you might even care less about what they got to say, because you know that you did your best on your personal appearance and only that matters. Take the power and own it.
