Psychologists are studying why we always think we'll have more free time in the future.

Zauberman and Lynch continue, “People are consistently surprised to be so busy today. Lacking knowledge of what specific tasks will compete for their time in the future, they act as if new demands will not inevitably arise that are as pressing as those faced today.”

In short, the future is ideal: The fridge is stocked, the weather clear, the train runs on schedule and meetings end on time. Today, well, stuff happens.
