Exercise your smile, build those muscles, see how long you can hold it, see how high you can hold it!
See how long you can hold it when looking at another, see how long it takes before they are smiling too!
Exercise it in traffic, at work, at school, while shopping, everywhere!
It's the only muscle that has an immediate positive impact on everyone you see.
It even works when you are alone.
Nobody cares about your biceps...
Smile!
