Don’t let the entire day get derailed by a setback. Also, don’t stop yourself from reacting and spiraling a little. Consider it “strategic spiraling” like letting out a fishing line instead of reeling in a fish so hard that you snap your pole.
Embrace the delay and immediately cross off an hour in your schedule. The setback has occurred, the day will not be as you once wished, but it can still be a good day.
By giving away some time when a setback occurs you allow yourself to purge it from your system and take some control over the time that you’re losing. It’s you that has decided that this next hour will be thrown away venting or fixing the setback or getting back on track, etc…
So throw the hour away and reset from there. No sense wasting an entire day when wasting an hour will do just as well.
