Positive thinking has come under a lot of fire recently from some ‘highly rational and intelligent people’ who consider it very fluffy and they believe makes them look less intelligent if they admit to practicing positive thinking.
However, as Harvard trained Psychologist Shawn Achor describes in his book The Happiness Advantage, a recent scientific study showed that doctors who are put in a positive mood before making a diagnosis consistently experience significant boosts to their intellectual abilities than doctors in a neutral state, which allows them to make accurate diagnoses almost 20% faster. The same study then shifted to other vocations and found that optimistic salespeople outsell their pessimistic counterparts by over 50%. Students primed to feel happy before taking math tests substantially outperform their neutral peers. So it turns out that our minds are literally hardwired to perform at their best not when they are negative, or even neutral, but when they are positive.
Of course, that’s not to say that successful people never get upset, but your effectiveness in all walks of life will fare better if you’re able to mindfully accept and let go of negative emotions, rather than dwelling on them. Think a little less about managing your problems and a little more about managing your mindset.
