The positive outlook that optimists project does not come from ignoring or denying problems. Optimists simply assume that problems are temporary and can be solved, so optimists naturally want more information about problems because then they can get to work and do something. Pessimists are more likely to believe that there is nothing they can do anyway, so what's the point of even thinking about it?
Confidence isn't optimism or pessimism, and it's not a character attribute. It's the expectation of a positive outcome.
Pessimists see problems as stemming from stable and universal causes, thus making them less susceptible to corrective action. Optimists, in contrast, view problems as temporary and resulting from specific factors that will either change or be changed.
