what is business exactly?

The New Webster’s Dictionary defines [busi*ness] n. ones regular employment, profession, occupation | ones personal affair, concern, duty | something requiring attention | active selling, transactions | a commercial firm or enterprise.
Ultimately, isn’t Business far more complicated than this? Don’t we have a much higher regard for the required investment into whichever Business we chose to be involved in?
We hinge our livelihoods on our Employment or our Company and we uphold a great deal of our Self Worth on our achievements, credentials and successes through Businesses and Careers.
We as People are driven to begin, create or build Businesses to express or share our inspiration or ingenuity. Just as it is People, that choose to work within specific Businesses. It is People that form the Teams who are inspired to drive the Business and People who are the Market that interact with the Business that aligns with their needs as a Consumer.
There in making Business a far more personal endeavour than just the mere turnover of transactions, numbers and Market definitions. Because in reality the core of Business is always People, it is an Economic and Marketable way in which we the People, can trade our loves, passions, skills, interests or continue generations of family investment and history.
