You've invented Crocker's Rules.

Ob has changed people's practical lives in some major ways. Not all of these are mine personally:

"I donated more money to anti aging, risk reduction, etc"

"I signed up for cryonics."

"I wear a seatbelt in a taxi even when no one else does."

"I stopped going to church but started hanging out socially with aspiring rationalists."

"I decided rationality works and started writing down my goals and pathways to them."

"I decided it's important for me to think carefully about what my ultimate values are."
