People are predisposed to think negatively. It makes sense – when our ancestors were hanging around the jungle, being able to spring into action at the slight sound of a snapping twig was a matter of life or death. It was a great thing then, because their fear and vigilance allowed us to survive into the 21st century. But now that most of us are trying to outrun deadlines instead of fanged beasts, we've come to feel the effects of negativity's close cousins – stress and depression.
One solution to these modern day problems contradicts the worldview of our prehistoric brethren: positive thinking. Studies have shown that positivity, or optimism, is linked to longer life, increased pain tolerance and better overall health. Optimistic people are also able to see the bigger picture, causing them to preform better at work and make better decisions under duress. Ultimately, they make more money and are more likely to get promotions.
Realists with belief in a better future
To be clear, optimists are not the happy-go-lucky suckers that people usually refer to when they throw around the word as an insult. They do not hold the Pollyannaish view that all is well in the world and that when their bosses or co-workers are making them miserable they should just swallow their problems and be grateful to be employed. That's just irrational.
Optimists can be perfectly realistic, just like pessimists. Where they differ is how they think about adversity and its causes. While a pessimist may feel a challenging project is almost insurmountable, triggering feelings of powerlessness, an optimist will begin thinking of solutions and start chipping away at the parts of the project they know they can handle first. The Happiness Advantage author Shawn Achor defines optimism as "a realistic assessment of the present, while maintaining a belief that our behavior will eventually create a better reality."
