A Sefer At Work

Whether he is standing in his shop or in the marketplace, every businessman should have a sefer in his pocket - such as a Chumash, Tanya, Mishnayos, or Tehillim - so that whenever he has a free moment he can reach a verse of Chumash, or a few lines of Tanya, or a mishnah, or a passage of Tehillim.

(Rebbe Yosef Yitzchak Schneersohn of Lubavitch)
