It's been said, "those who do not remember the past are condemned to repeat it." On the other hand, we can also be preoccupied with the future. Whether it's economic or weather forecasts or the imaginings of science fiction, we want to know what's going to happen next.
We're locked into a time continuum of past, present, and future. The only way to be free from repeating history or preoccupation with the future is to know and trust in the One who is eternal, who holds the future in His hands.
