The best driving advice I ever got was "you get there when you get there."
Miss a turn? It's okay. You get there when you get there.
Left the house late? Nothing you can do about it now. You get there when you get there.
Stopped by a train, or an accident on the highway? It's out of your hands. You get there when you get there.
I know all of these things can be anxiety-inducing. But by the time you're in the car experiencing them, no crazy maneuver will make a meaningful difference in the time it takes to get where you're going, and that maneuver will be at the cost of your safety and others.
Nothing is more important than your life.
You get there when you get there.
