This kind of creative visualization can help in a number of ways. It can motivate ("I can't wait!"), soothe ("Licensed or not, what's most important to me is unchanged"), and prepare you for the outcome ("It's just a matter of time").
Let's look at the last one. What will you do the day you pass your test? How will you celebrate? This is a little bit tricky. Putting together a licensure celebration involves some hubris. You don't know that you're going to pass. It's a plan. It's a hope. But you do know that you're going to take the exam. Does it make sense to arrange an "I took the exam" celebration? Pass or not, you may want to have people close to you around after you've crossed the licensing exam finish line. It depends upon you (and the people close to you).
Whether or not you arrange a test-taking party with others, consider at least putting together one for yourself. Take a little time after the exam to pat yourself on the back, give yourself a gold star. You did it. You studied, you worried, you got prepared, you sat for this giant exam. Regardless of result, it's an achievement. It deserves to be marked. Here's from us in advance: Congratulations!
