The young doctor should look about early for an avocation, a pastime, that will take him away from patients, pills, and potions . . . No [person] is really happy or safe without one, and it makes precious little difference what the outside interest may be – botany, beetles or butterflies, roses, tulips, or irises, fishing mountaineering or antiquities – anything will do so long as he straddles a hobby and rides it hard.
But do not get too deeply absorbed [in your work] to the exclusion of all outside interests. Success in life depends as much upon the [person] as on the physician. Mix with your fellow students, mingle with their sports and their pleasures. … You are to be members of a polite as well as of a liberal profession and the more you see of life outside the narrow circle of your work the better equipped you will be for the struggle.
~ William Osler
