In my third year of college, an entrepreneurship professor told our class on the first day, “Know yourself”. He was referring to business–in particular starting a business–and saying that if you don’t know yourself you won’t get anywhere. He’s right.
As a person, you must recognize your strengths and your weaknesses and know them inside and out so you know how to win and how to fail.
I cannot imagine a better motto for life, or for fashion. Know yourself and know what looks good on you and what you can do for you. Never betray that knowledge. Follow this, and you’ll always understand and have your own style without getting swept away.
