Running a business is not kid's play. When I first started out doing consultancy work, I thought I was in business. How wrong was I. I was merely changing employers.
As an employee, the boss is the paymaster. As a self employed person, I am the paymaster.
And as a paymaster you have to wear many hats and pick up many skills, FAST! You have to learn how to sell (your skills), learn how to manage people (employees, customers, suppliers), learn how to market your products (advertising, the media), learn how to operate the gadgets (and also learn how to fix the gadgets when it fails) and much much more.
Along the way, you pick up 'business skills' or 'entrepreneurial skills'.
