Comparing it to trying to drive a car while the parking brake is engaged illustrates that ignoring essential preparations can lead to failure or frustration.
Essentially, the quote emphasizes the importance of identifying and resolving foundational issues before moving forward with a plan or action. It suggests that success often depends on proper groundwork, much like releasing a parking brake before driving a car.
