The Kozhiglover Rav, Rosh Yeshiva of Chachmei Lublin before WWII, writes that the Torah learned in these few days between Yom Kippur and Sukkos is even more precious than the Torah learned at any other time during the year. The Midrash writes that Sukkos is, "Rishon l'cheshbon avonos," the beginning of a new count of aveiros for the new year (see his hesber of what this means). Until then, we have a completely clean slate. The merit of our learning is more than equivalent to the untainted hevel pihem of tinokos shel beis rabban because not only are we also untainted by cheit, but we have the additional zechus of being metzuveh v'oseh.
There is a lot to do this week: a sukkah to build, lulav and esrog to buy, helping the wife with the shopping and cleaning. Still, it's critical to try if at all possible to squeeze in some extra learning to make these days count.
