Most people would define optimism as endlessly happy, with a glass that’s perpetually half fall. But that’s exactly the kind of false deerfulness that positive psychologists wouldn’t recommend. “Healthy optimists means being in touch with reality.” says Tal Ben-Shahar, a Harvard professor, According to Ben- Shalar,realistic optimists are these who make the best of things that happen, but not those who believe everything happens for the best.

Ben-Shalar uses three optimistic exercisers. When he feels down-sag, after giving a bad lecture-he grants himself permission to be human. He reminds himself that mot every lecture can be a Nobel winner; some will be less effective than others. Next is reconstruction, He analyzes the weak lecture, leaning lessons, for the future about what works and what doesn’t. Finally, there is perspective, which involves acknowledging that in the ground scheme of life, one lecture really doesn’t matter.
