While medicine is your vocation, or calling, see to it that you have
also an avocation--some intellectual pastime which may serve to keep
you in touch with the world of art, of science, or of letters. Begin
at once the cultivation of some interest other than the purely
professional. The difficulty is in a selection and the choice will
be different according to your tastes and training.
--Osler, _Aequanimitas and other Addresses_.
