“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. Often, the best part of your work will have nothing to do with potions or powders, but with the exercise of an influence of the strong upon the weak, of the righteous upon the wicked, of the wise upon the foolish.” As true today as it was 100 years ago by Sir William Osler.
