Mishnah 1: “These are the things that have not measure: the Peah (corners) of the field, the first-fruits … and the study of the Torah.”
Measurement is very important. Consider dosage. Get the dose wrong and the medicine can turn into poison. Substitute two cups of salt for two cups of sugar, as I did in a spice cake last Christmas, and people who usually regard you highly and warmly will say really mean things at your Christmas table’s finale.
