Maybe you’re a glass half-full kind of person. Or you might be quite the opposite –a born pessimist, prone to imagining the worst possible outcomes. Or maybe, like many people, you swing between the two, depending on your feelings and the current situation. While some might be happy to identify themselves as one or the other, for others it isn’t quite so cut and dried. Whatever your perspective, there can be something quite attractive about an optimistic outlook: being able to see the good in things, looking for the bright side and spotting the positives.
