"But what’s funny is that my favorite bookstores that I’ve loved shopping in are crazy junky old used stores with books piled everywhere, with the owners smoking, and all the books smell like cigarette smoke. I love stores like that. Yet if my staff leaves anything lying around, I’ll say, “Get rid of this mess! We have to keep everything clean!” It’s so funny. You can sit in the quiet of your mind and say, “I will be this sort of spouse, I will be this sort of friend, I will be this sort of daughter.” Then you go into daily life and you are exactly the spouse, friend, and daughter that you have no choice but to be. The dominant personality is indomitable, and I believe that bookselling is the exact same way. You can say, “I will have this kind of bookstore,” but you can no more control that than what kind of person you are."
— Sarah McNally in this interview with Poets & Writers, which I will probably keep quoting from.
