Good article. These are hard learned lessons. I learned them all the hard way myself. Its funny but in business and entrepreneurship most don’t pay attention until they have their back against the wall. This article should be made into a one semester course required by high schools and colleges. Business failure do to our cultural distaste for the mechanics of insuring payment for service has created an ignorant blind spot resulting in an epidemic of chapter 11_filings. Everything is about the Benjamin’s, money is not a 4 letter word.
