An amazing thing about us humans is that we are able to project our minds into the past, the present, and the future, wondering, and pondering, and imagining over what was, what is, and what is to be.
Animals can't do that.
And sadly, many humans don't. Not because they can't. But because they fill their minds so full of other people's thoughts that they leave no room for their own.
