When something in your business starts to go south, it's natural to focus on the things that are going wrong. The problem that many entrepreneurs make is to put all of their energy on what's going wrong and ignore the aspects of their business that is going right.
In times like this, it is helpful if you can stay focused on what is working, while you are addressing the challenges you must overcome. This is important because if we ignore what is working, we will inevitably find that ship is sinking and by the time we realize that, it may be way too late.
Running a business is a careful balance of overcoming challenges, putting out fires, maintaining status quo, and developing future growth. Know when to wear each hat and your business will be better for it.
