Blind optimism is not healthy.LOL!
Perhaps...But, it sure beats blind PESSIMISM. :o)
Well, neither is good. But at least blind pessimism tells you there are potholes in the road. Blind optimism has you hitting one a full speed and losing a wheel. Blind optimism tells you that you live in a marshmallow castle with a strawberry moat when pessimism has you checking the structural integrity of castle walls and the moat for sharks.
Yes, if given the option between ONLY blind optimism or pessimism, I’ll take the P because at least I’ll be ready when the barbarians storm the gates.
