Sack up and do it.
Busy at the gym tonight - I was sharing a bench/rack just about the entire evening. I was spotting a guy who was benching my 1 rep max for reps - but our attitudes were way different going into the exercise.
He would say something like this: “I’m going to try, TRY for 6, maybe 8 reps. I’ll probably need help on the last couple though, ok?”

If that’s your attitude going into anything, wouldn’t failure be acceptable? Set your standards low and you’ll never fail at anything. Perfect. Set phasers to “mediocre” and go have a lukewarm bath because you’re probably overtrained if you lift for more than 3 hours a week.
If you suck, stop. Make enemies with that bar/road/dumbbell, grab it by the throat, and lift/pull/press/run it until you feel like stopping. Then go for a couple more reps, just to show it who’s boss, and come back the next day to murder it again.
