Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.
Coaching is a form of development in which a person called a coach supports a learner or client in achieving a specific personal or professional goal by providing training and guidance. The learner is sometimes called a coachee. Occasionally, coaching may mean an informal relationship between two people, of whom one has more experience and expertise than the other and offers advice and guidance as the latter learns; but coaching differs from mentoring in focusing on specific tasks or objectives, as opposed to more general goals or overall development.
Somewhere in the past. organizations were quite simple, and 'doing business' consisted of buying raw material from suppliers, converting into products, and selling it to customers... For the most part owner-entrepreneurs founded such simple business and worked along with members of their families. The family-dominated business still accounts for a large portion of the business start today.

However successful a man may be in his own business, if he turns from that and engages ill a business which he don't understand, he is like Samson when shorn of his locks his strength has departed, and he becomes like other men.
