Chekhov

Most people think of Anton Chekhov as one of the greatest short story writers but few remember that he is also a physician. I ran across this quote in a letter he wrote and really liked it:

"Medicine is my lawful wedded wife, and literature is my mistress. When I've had enough of one, I can go and spend the night with the other. You may well call this disorderly conduct, but at least it stops me getting bored, and in any event I am sure that neither of them is the loser from my infidelity. If it were not for medicine I would not be devoting my leisure moments and my private thoughts to literature; I haven't the discipline to do so."
