     Like a flower with a pleasant scent, your smile can draw people close enough to see inside you.
That's Smile Power. A smile has the power to radiate the qualities that make you beautiful on the
inside-kindness, friendship, honesty, respect, patience, and self-control. So please give smiles away
like flowers. Let your smile be an invitation for others to get to know the great person behind the smile.
Then let people see that your smile doesn't stop at your mouth. It goes all the way to your heart. On the
other hand, we are drawn to people who smile and we want to know a smiling person and figure out
what is so good. Frowns, scowls and grimaces all push people away-but a smile draws them in.
2. _____
     Next time you are feeling down, try putting on a smile. There's a good chance you mood will change
for the better. Smiling can trick the body into helping you to have a good feeling. So smile is a good state
of mind, you have a smile, then you will have a better feelings. So when you are smiling you lighten up the
room, change the moods of others, and make things happier.
3. _____
     The muscles we use to smile lift the face, making a person appear younger. Don't go for a face lift, just
try smiling your way through the day-you'll look younger. Then you will feel better and have more
confident, thus are more likely to be promoted, and more likely to be approached. Put on a smile at
meetings and appointments and people will react to you differently because of your confidence.
4. _____
     Stress can really show up in our faces. Smiling helps to prevent us from looking tired, worn down,
and overwhelmed. When you are stressed, take time to put on a smile. This is because when you smile,
there is a measurable reduction in your blood pressure. You can sit for a few minutes, take a reading.
Then smile for a minute and take another reading while still smiling. You will be happy to see your stress
disappears quickly.
5. _____
     Now try to think of something negative without losing the smile. It's hard. When we smile our body is
sending the rest of us a message that "Life is Good!" Stay away from depression, stress and worry by
smiling. So smile is a positive state of mind, every time you smile at someone, it is an action of love, a gift
to that person, a beautiful thing and then other people will also answer your smile.
