Transition, as an in-between state

Transition is also called liminality by psychologists - a state where you are neither in the state you left nor entirely in your new state. This in-between state creates an identity crisis, even in good transitions.

But they are really a predictable and integral part of life and happen regularly. Author Bruce Feiler interviewed hundreds of people and found that a major life change happens, on average, every 12 to 18 months. Even huge collective transitions such as the pandemic occur with regularity.
