Our experience is built from things that have happened in the past. It is built up from things we learned, things we experienced, and the things we imagine could happen. All of this is built on the past and our best bet at extrapolating it to the future.
Experience is important. It helps us to understand how situations tend to go. We learn how to deal with different types of people. We learn what can go right or wrong across the various things we work on. These things we learn are largely the building blocks of interactions, not actual outcomes.
Outcomes change with every new event because, like experience, they are built on the past of the participants. Those collective pasts add up to something new and different because everyone tries to avoid the errors and issues that they have previously experienced. Trying to avoid bad things from the past require new results.
Therefore, the past requires the future to be different than the past. Using the past to exactly indicate the future is a bad call. The past is an input into predictions but it says that things must change.
