Identification.

Spending the day feeling at 80% at best and staying up late demonstrates an inability to learn a lesson. Freely admitting to that doesn't help any, but at least I'm identifying the problem.

Another problem I identified this afternoon was being unable to address people in the gym when they're being loud enough I can hear them over whatever podcast I'm listening to. Cranking up the volume to drown them out would be to put it at the maximum, which wouldn't be a fix.
