The “hole” that is referred to in the phrase “the hole gets deeper and deeper” can have many different interpretations, depending on the context. It could refer to a physical hole in the ground, a financial debt, or a problem that seems to escalate and become more difficult to resolve. Regardless of the specific meaning, the phrase suggests that a situation is becoming increasingly problematic, and that it is important to take action to address it before it becomes even more difficult to manage.
One of the most important things that can be done in any situation that seems to be spiraling out of control is to prepare. Preparation can take many different forms, depending on the situation, but the goal is always the same: to reduce the risk of the situation getting worse, and to increase the chances of finding a successful solution.
