I just spent the last five hours with Paul dredging up old algebra skills in an attempt to finally, once and for all, figure out HOW MONEY WORKS.
Okay, that's not the question we were trying to answer.
The question is: How can I know my business is financially healthy?
It shouldn't be hard. There are all kinds of axioms, including "Concern yourself with making your money, spend it later." A business without profits is not a business for long. Etc. etc.
