... You advise me not to hunt after two hares, and not to think of medical work. I do not know why one should not hunt two hares even in the literal sense.... I feel more confident and more satisfied with myself when I reflect that I have two professions and not one. Medicine is my lawful wife and literature is my mistress. When I get tired of one I spend the night with the other. Though it’s disorderly, it’s not so dull, and besides neither of them loses anything from my infidelity. If I did not have my medical work I doubt if I could have given my leisure and my spare thoughts to literature. There is no discipline in me.
