There are two types of reasons people predict the future.
The first type is common to everyone—we try to predict the future to see how well we know the past to guide us to accurately anticipate what will happen next.
The second reason is more of the psychopathic reason, and unfortunately is the hidden reason for many of us; the second reason for predicting the future is because we prefer our prediction to become the future. Sometimes, this is called “wishful thinking”.
Believing something will happen and agreeing that something should happen are two different things. Don’t be confused.
