"Scientists have shown that optimism literally expands your peripheral vision, allowing you to see the big picture more than you typically do. Studies show that optimists have lower stress levels and more stable cardiovascular systems, and on average, live seven and a half years longer than pessimists. While pessimists are more likely to succumb to job pressures, optimists see job stress as temporary and external to them. If you look for the upside of a career obstacle and search for the opportunity in the difficulty, you’re more likely to overcome hardships and scoot up the career ladder faster and farther than a negative attitude allows. An optimistic mindset doesn’t arm you with magical joy juice, and you don’t become a smiley-face romantic looking through rose-colored glasses. You’re able to take realistic steps to cope with work stress instead of succumbing to it. If you’re not a natural-born optimist, no worries. You can learn coping skills to deal with career challenges."
