Despite its structure, introspection is neither a forced process nor a deliberate action. There is no "have to". When practicing this technique, we stay with an action, thought or emotion for as long as we can before moving on. We go on looking, noticing, and appreciating, when suddenly, something may just become clear since our mind was made available to see and understand. Today, as we look back at our day, we ask ourselves if we made a conscious choice to be happy and introduce that concept to our mind.
