Arguably both ‘extremes’ can become an excuse for inaction, pessimists may think “why even try if it probably won’t help” while optimists may think “it’ll resolve itself / look at the bright side.” Similarly, both can be strategies for coping with disappointment. And can become a tiny bit delusional.

But at least optimists live in blissful ignorance lol. I think people underestimate an optimist’s ability to see problems as just solutions waiting to happen.
