Hi,
Your "rant" showed a truly negative outlook on life in general. I truly feel sorry for you.
I could go on as long as you did, or longer I am sure, but I will just mention a few other optimists.
Marie Curie, Thomas Edison, Henry Ford, Jonas Salk, Leeuwenhok, Charles Best, Walt Disney, Alexander Fleming, etc, etc.
All of the above and many others imagined something that hadn't existed prior to them conceiving it. It was their optimism that allowed them to follow through and create something that was beneficial to mankind.
