Rav Chaim Kanievsky on Succos

In the Kanievsky home, preparations for Succos started literally right after Pesach, as the Rebbetzin put the leftover matzah on the side, to be ground into flour that would be used when she baked challah for Succos. An esrog was chosen two months before the holiday, and Rav Chaim himself would go to pick the schach. Then, as the festival started, the lofty levels of rejoicing and dveikus began.
