I told myself I would relax after I got in. Then I started searching for the course structure, book lists, preparation advice, student jobs, and every possible way to avoid arriving behind. At some point I was studying for a semester that had not started because being excited felt too close to being unprepared. I closed the documents for a week. Nothing collapsed. The degree remained available. Preparing is useful. Resting before a major move is also preparation, even if it produces no checklist item.
