Power—it's a nebulous thing. There's the kind of power people try to claim (remember how Jafar said that the universe was his to command? To control? Yeah, not so much) and then there's real power. The kind of power the Elf on a Shelf has on your average five-year-old on December 23. Good news—as a cardiologist, your power will be much closer to that of the Elf than that of our old buddy Jafar. Sigh of relief.

Good cardiologists develop a rapport with their patients and share mutual respect. After all, you want your patients to follow your guidelines because they trust your advice, not because of fear. A good heart doctor knows it's important to motivate and encourage patients rather than browbeat them. Unless, of course, you really want that patient to switch to a different doctor and give you a bad review on Yelp.

Because they are specialists of the heart, cardiologists have tremendous influence on patients and their families. The medications, lifestyle changes, and surgery recommendations a cardiologist gives a patient can literally make the difference between a shortened life or living long enough to see their grandchildren go off to college.

Hey, a great cardiologist might even help a patient live long enough to see their great-grandchildren go off to college. To say nothing of the time travel and hovercrafts that will surely be around by then, too.
