*Excerpt from my book PERFECT BALANCE[r1]
Optimists see the glass as half-full, and it stands them in good stead. Between 1962 and 1965, a group of investigators from the Mayo Clinic performed personality testing on nearly five hundred study participants. They recently followed up on them some thirty years after the original test and found not only that the “pessimists” has lower overall scores in terms of their health, but that over the three intervening decades, the “optimists” had about a 50% higher survival rate. Other studies have had similar results. Psychologist Dr. Richard Wiseman, author of The Luck Factor, has shown that the way we assess various situations changes how effectively we accomplish our goals. And a positive outlook wins every time.
