No, there's nothing wrong with being optimistic. It's a good way to be, it's healthy. I personally would LOVE to be what I call a "perma-optimist", and being able to see the bright side and silver lining of everything, but my problem is I didn't grow up with a normal childhood, and I don't live a normal life to this day, and as such, it's difficult for me to be optimistic about anything. That's not to say I'm pessimistic about everything either, it's just I prefer to have this kind of outlook on life: I'd rather not look forward to something and be pleasantly surprised, as opposed to get my hopes over something and be disappointed.I don't recall you Snowth ever telling someone "Stop being optimistic!" You just said what you personally felt about a project and that was that. Well it should go both ways shouldn't it?
Perhaps I may be just a little TOO opininated, I do feel the need to speak my mind when I feel it really counts, but again, like I said, it's not just me, I see other people are now coming forward, speaking their minds as well, sharing their different opinions, only to be basically almost scolded like a little kid who doesn't do what the superiors want him to.
It's almost kind of like the way Caroll Spinney said Jon Stone was with him: on the set, they did work well, and were very professional with each other, but when the cameras weren't rolling, Jon basically treated Caroll like crap for reasons even Caroll never figured out.
