Your skin . Everyone wants perfect skin. Some are born with it - most of us are not. Cleanse and moisturize at least twice daily, do what you need to do to take care of it, but don't wail over it. Eat well, stay calm and relaxed, exercise, and your skin will glow.
Every face is beautiful when embellished with a geniune, heartfelt smile.
Smile at people you see, whether or not you know them. Let happiness fill your heart and your inner beauty will naturally show. One of the most important things that prevents people from looking their best is their posture. Pull your shoulders back and stop slumping, don't shuffle but take calm strides, pull your neck back and not out like a hen, hold your chin up and look people in the eye. Then smile with confidence.
