To help envision the goal of becoming a cardiologist, Zai would most likely need to go through "process visualization." This involves imagining the steps and processes required to achieve a goal, such as getting into medical school. It focuses on the specific actions and milestones Zai needs to take, which can help clarify what needs to be done and reduce anxiety about the journey ahead.
While other options like outcome visualization and goals are also important, process visualization specifically emphasizes the steps involved in reaching that outcome. Implementing intentions focuses more on planning specific actions rather than visualizing the overall process.
