You don't have to finish early to do that. Set time aside to travel while you pursue your doctorate (I assume you want to be a doctor?). Take advantage of school breaks, summer vacation. Even take a semester off and return to finish the program when you feel ready. There's no rush.
If you want to do something specific like radiology or anesthesiology, there are certification programs and technical schools that don't take as long as medical school. You can even take online classes. Up to you.
Best of luck.
