"everything is cyclical"

I love this! Everything IS cyclical. I read once that history is a catalog of human nature. And since human nature hasn't changed much in thousands of years, we can probably expect people to act similar in the future, but with different technology. And if there were bad times before, there will be bad times ahead, AND there will be good times ahead. The Bad and the Good never last forever and one will be replaced with the other given enough time.
