Related to part of what you said. I've worked in a half dozen different industries; I've worked in little companies with a half-dozen employees and globe spanning companies with tens of thousands and employees. They all think that they have special unique problems that nobody else has - 90% of it is the same problem I've seen in other companies in different industries, with different industry specific acronyms and words.

Every damn job, the same basic problems over and over, with the insistence that these problems are specific to the industry and usually to that specific company and that specific product.
