Pulling into the rest stop isn’t giving up on the road trip. It’s how you finish it.

A break taken halfway along is part of the trip. Driving until you are unsafe is not commitment, it is a miscalculation about what the trip requires, and the cost lands later on someone else’s schedule. Nobody who arrives thinks about which stops they made. They think about arriving.

Build the stop into the plan before you need it, since you will make a bad decision about it once you are tired. Put the break in the calendar the way you would put in a deadline. Then take it fully, without apologising and without cutting it short.
