Being lucky repeatedly can make caution feel unnecessary right before caution becomes necessary.

Repeated good outcomes wear down vigilance. Every time the precaution turns out to be unnecessary, it feels a little more like theatre, until skipping it seems like maturity rather than risk. The trouble is that caution earns its keep rarely, and the day it matters is not announced in advance.

Find a safeguard you have quietly let lapse because nothing has gone wrong. Reinstate it once, this week, without waiting for a scare. The whole value of a precaution is that it is already in place before you need it.
