from the inside. That's because they don't have time or energy to belabour the appearances of beauty on the outside.
They live without malice, anger, jealousy. They serve others in some way. They smile, and they provide a beacon of hope to the despondent and the people in need. They rarely need what they aren't willing to give in return.
In fact they give more than they take.
Beautiful people are gracious and kind, generous and loving. Their hearts have all the eloquence of a mozart concierto.
Acknowledge and appreciate the beautiful people in your life. Because it's damn tiring looking after all the needy, jealous and angry ones and doing a bit more of that appreciation and acknowledgement thing, may make you a bit more beautiful too.
