No matter who you are and no matter what business you are in, something always happens in a business that you never expect (and more than once).

This is why you need to constantly look for more money or make sure you always have available cash resources. These unexpected occurrences can put you out of business if you’re not careful and they’re inevitable. 

This is why your salary needs to be conservative; this is why you need to cut overhead, this is why you cannot withstand slow paying customers and this is why you need to cover your operating losses. I have seen so many businesses go under because they were not prepared.

Don’t be like them and make sure you have enough cash resources available to deal with any emergency that may come your way.
