To smile is a beautiful thing. Your smile illuminates the world and creates good feelings within you and for those around you. So your face has a wrinkle or an uncooperative hair. In the big picture of life, this is a small thing. Yes, you should try and look your best. The smile on the face is the icing on the cake. No matter whether man or woman, young or old, everybody likes to see a smile. It will lift you no matter what the circumstance.
Years to come others will remember you fondly with a smile on your face. Give it up!
