The practice of medicine is an art, not a trade; a calling, not a business; a calling in which your heart will be exercised equally with your head.

The practice of medicine will be very much as you make it - to one a worry, a care, a perpetual annoyance; to another, a daily job and a life of as much happiness and usefulness as can well fall to the lot of man, because it is a life of self-sacrifice and of countless opportunities to comfort and help the weak-hearted, and to raise up those that fall.
