An Interesting Smile?

The Scotsman - UK - Smile may be secret of success:

"Many people assume that success in itself - getting the best job, hooking up with the perfect partner and raking in the cash - is the key to being happy in life.

But psychologists in the United States say that if you want to be successful you might just have to put on a happy face first.
The researchers from the Universities of California, Missouri and Illinois examined the connections between desirable characteristics, life successes and well-being in more than 275,000 people.

They found that it was happy individuals who were predisposed to seek out and undertake new goals in life leading to success, which also reinforced their already positive emotions. "
