If you date someone who isn't very good-looking but makes you laugh, you will never forget it.
Something you wore three months ago, maybe you don't wear it again. I am a great believer that if something looks very good on you, you can wear it again, and it's not the end of the world.
Keep in shape: if you look good, you will feel confident.
You wouldn't know it but I'm no good at... cooking. My chef does that.
