I just want to wish everybody a Kesiva V'Chasima tova - a year of health, parnassah, and peace and a geulah shleima.
One thought for Rosh HaShanna: Many people have the custom not to do any sins on Rosh HaShanna because the Hebrew word for "sin" - חטא - has the same gematria as the word חטא which means "sin"! (Amazing but true!) וסימנא מילתא היא.
שנה טובה ומתוקה
