It is said that the beauty lies in the eyes of the beholder.But I think beside this you can make yourself more sparkling with very tiny things.
What you have to realize is ..real beauty is the self-awareness that makes YOU, you. It is having sparkle,poise,serenity & confidence.It is having an awareness that makes everyone you come in contact with fell that you are a very special & attractive person.
More than anything else, beauty is being able to make the best of yourself.
Adopt the positive rather than the negative approach. remember, negative thought can be very damaging. Feel good about yourself - it is not just your beautiful looks that attract people, but also the really beautiful person you are inside that shows & attracts people to you.
