“Business” is not a skill.
“Businessman” is not a job title.
“Business books” aren’t about business.
So what is there?
Real skills, such as the ability to resourcefully produce something from vision, either through the work of your own brow or through leading others (or both).
Real jobs, such as leading, accounting, marketing and development.
Real books, such as autobiographies documenting the experience of others, or tombs of wisdom on very specific subjects.
