No matter which healthcare profession you choose to pursue, whether it is medicine, dentistry, optometry, or something else, all of the people making admissions decisions will expect you to test this decision thoroughly and thoughtfully.
In addition to strong academic performance, you should also volunteer extensively, shadow professionals in your target field, and, in general, choose activities that allow you to mature and appreciate the complexities of your target profession more fully.
It is also important to know what is expected of you; what is right for medical schools may not be right for physician assistant schools, dental schools, or other health professions programs.
