Longing for Shabbos All Week
Rav Asher of Stolin taught that a person should look forward to Shabbos throughout the entire week, thinking to himself, "When will Shabbos come?" He added that on every day of the week one should remember the holy Shabbos by preparing, if possible, something in its honor.
