What is it like to have a job in buisness management?

Like what is it like to own your own buisness or be a manger or even a CEO of a company?

Being the CEO of your own business is the best achievement one can ever make. The reason is because you ought to make your own decisions without pressure from the Board Members.
Another good thing is that you can achieve what Maslow terms as "Self Actualization" in his hierarchy of needs i.e you do things your own way and other people follow.
