Blind Positivity vs Optimism

I think there's a difference between blind positivity and optimism. People keep accusing me of being naive because I declare myself an optimist. Optimism is the undying belief that the future is bright. But I can be totally realistic that I'm in a dark hole right now. That's optimism. It's not like everything's fine. Everything's good. There are different things, even though they may both be about the affirmative future. And so to that point, I believe when I take advice that didn't work out well, I believe that I still had that experience for a reason.
