This is not a far fetched story! I am actually in that state right now. In one of my businesses! I have not had clients for a while. The few who come can't afford, Some will pay a part and disappear with the balance. Some say I'm too expensive Some say they don't need it after they start. Others say they know where to get the same service and even better and cheaper. Guess what? For the past 2months, I halted all it activities. Ask myself deep questions on why I started that particular business in the first place. Who did i see as my ideal client? Can such clients pay? Do they actually need it? What was my marketing strategy? With all these questions to myself: only then did i notice i had a great Business but selling it to the wrong clients. I reinstituted my clients and my marketing strategy and i hope in the next 3months all will get back to better and greater. 

My advice to all entrepreneurs: young, older and oldest, always make out time for your Business to be sure it's on track
