Rabbi Yaron Reuven gives a few details of how to celebrate Sukkot. One of the most important mitzvot of Sukkot is building a KOSHER Sukkah and dwelling in it. Including eating meals, and for a man, learning Torah and sleeping in the Sukkah. And all the while being V'Samachta B'Chageka! You have to be comfortable and happy, if you're not comfortable, it's not a Sukkah.
