Smiling Opens the Heart

Good feelings for others are like ointments that heal wounds and re-establish friendships and relationships. Good feelings are generated in the mind, are transmitted through your attitude and are reflected in your eyes and smile. Smiling opens the heart and a glance can make miracles happen.

SMILE IS A COOLING SYSTEM OF HEART,
SPARKLING SYSTEM OF EYES, LIGHTING SYSTEM OF FACE, RELAXING SYSTEM OF MIND....
SO TO ACTIVATE ALL YOUR SYSTEM
==ALWAYS KEEP SMILING==
