We've all heard that a smile can be incredibly powerful. However, research has also shown that it is a contributor to your overall success in business and love. Researchers have reviewed photos of couples and found that those who were not smiling in their early photos together were 5 times more likely to experience divorce.
Additionally, other researchers found that in reviewing the early sports photos of professional ball players that those smiling in their early rookie cards were significantly more likely to experience success in their professional careers.
The key to this is the link to optimists. Those who are more optimistic - and that's what smiles tend to show - find it easier to get along with people and to expect good things to happen to them, thereby contributing to their success in marriage and, at least, in professional baseball!
