Sefer Ha’mitzvos Ha’Katzar (The concise book of mitzvos) By the Chofetz Chaim
This book lists the Torah mitzvos that can be observed today
Second Section – the Negative Commandments
154. It is a negative commandment “do not do any work on Shmini Atzeres”
As it states in Vayikra (Leviticus) 23:36, “The eighth day shall be holy… a day of assembly, no work shall be done on it.”
This applies in all places and at all times, for men and for women.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
