Pessimists, on the other hand, will often give up pursuing the goal. Michael Scheirer of Carnegie Mellon University and Charles Carver of the University of Miami found that when optimists are faced with a barrier, they believe the goal can still be achieved. When pessimists accurately perceive their performance, these individuals often cannot find the motivation to continue a particular pursuit. For optimists (in contrast to pessimists) successful tendencies proliferate throughout the optimist’s daily living (even when overestimated). However, Heifetz and Yossi found being optimistic changes the structure of one’s environment. Intuitively one would assume this would lead to trouble. Optimists, on the other hand, are likely to self-evaluate themselves as more effective than they actually are. However, one of the many differences between optimists and pessimists is that pessimists are more realistic about their performance – by way of either underestimating themselves, or more likely, giving themselves a realistic self-evaluation. These results run contrary to what one would expect. In the paper, On the Evolutionary Emergence of Optimism, researchers Aviad Heifetz and Yossi Spiegel show that high performing individuals are regularly found to be overly optimistic. When you evaluate your own performance, there is evidence to show that over the long-term you are better off overestimating your abilities.

Science gives you permission to overestimate your abilities It’s been described as an individual’s expectation that in the future, good things will abound, while negative things will happen rarely. Dispositional optimism is a well-studied personality trait. Let me set forth the argument that in a world of people trying to reach their potential, optimism is the desired course.
