Never Say "I've Seen This Before"
The most dangerous words in any expert's vocabulary, and the three rules that open Pirkei Avot.
2 minute readPirkei Avot (Ethics of the Fathers) is a book about character, not law. So why does it open with a list of who handed the Torah to whom, starting with Moshe at Sinai?
Pirkei Avot (Ethics of the Fathers) opens with a chain: Moshe received the Torah at Sinai and handed it on, generation by generation, to the Men of the Great Assembly, the sages who led the Jewish people at the start of the Second Temple period. Bartenura, the classic 15th-century commentator on the Mishnah, explains why an ethics book starts this way: its character lessons were not invented by the sages. They too were given at Sinai. Then come the Great Assembly's three rules: be patient in judgment, raise up many students, and make a fence around the Torah. On the first, Bartenura says: even if the same case has come before you two or three times, do not say "I have already ruled on this." Wait, and think, before you decide.

Slow down on the cases you think you already know
Expertise is pattern matching. After a year in a job you have seen most of the customer complaints, most of the bugs, most of the candidates. That makes you fast. It is also how experts make their worst mistakes: the moment your mind says "I know this one," it stops looking. Bartenura's reading of "be patient in judgment" is aimed at exactly that moment: not the hard case, but the familiar one.
The other two rules are for the same expert. "Raise up many students": Bartenura says Torah is taught to every person, without first checking whether he is sincere, as long as he is not known for bad conduct, and that someone who taught when he was young should keep teaching when he is old. "Make a fence": a guardrail you set for yourself so you never get near the line. Never sign a contract the day you get it. Never round a number on an expense report.
And the chain itself is the point. The advice in this book is not a productivity hack someone came up with last year. It came to you link by link from Sinai. Do what they did: live it, and hand it on.
Pick one decision you are about to make on autopilot today. Before you decide, ask one more question about it than you normally would.

Why an ethics book opens with Sinai
Bartenura notes that every other tractate of the Mishnah explains mitzvot, while this one is all character and conduct. Since the wise men of other nations also wrote books on how a person should behave, the chain comes first, to say where these teachings come from.
Be patient in judgment
Raise up many students
Bartenura reads this as a disagreement with Rabban Gamliel, who allowed into the study hall only a student "whose inside is like his outside" (Berachot 28a). The Great Assembly teaches that Torah is taught to everyone, without checking each student first, as long as he is not known for bad conduct. A second reading: one who raised students in his youth should keep raising them in old age (Yevamot 62b), as Kohelet (Ecclesiastes) says, "In the morning sow your seed, and in the evening do not rest your hand."
Make a fence for the Torah
His examples are the rabbinic laws that surround the Torah's laws, like the rabbinic restrictions of Shabbat, which keep a person a step away from the Torah's own prohibitions.
