When you miss a turn, the GPS automatically recalculates. It almost instantly finds another way to the same destination. Maybe it’ll ask you to double back. Perhaps, it’ll come up with an alternative route. Even when you keep missing turns or road works pop up, it vigorously keeps recalculating and prompting you to follow its instructions.
Comparing humans to GPS’ isn’t fair. GPS’ consisting out of hard- and software, don’t get frustrated or tired, provided they have enough power to run. Although the way these devices go about their business is certainly something I envy.
When we set out to reach a goal, we’re bound to encounter an obstacle or two. We might have even reached our destination unknowingly and flew right past it.
In the face of adversity, never lose track of your goal. Keep recalculating your route until you get there.
