Some folks can foresee what others are too blind to see, figuratively. They can imagine great things and make them happen. Others stand by and tell them it is futile. Impossible. Never gonna happen. It happens. What we think we know today may change with a new view tomorrow. I can't imagine anything we "know" that may not be subject to change. I know. Death is certain. What is not certain is what if anything comes after. No one alive can possibly know that. At least I don't think so.
