Control, control, control. Everyone wants to control.
Boss wants to control his employees. Big boss wants to control the mid level bosses. Junior fellows try to exert control over the new recruits, who in turn try to control the interns.
Employees in general hate the upper echelon control freaks. And so they want to start-up, be their own bosses. Only to realize, that there too, the control lies with the customer, because as we all know, customer is king.
Even the CEO lives a shackled life, his doings controlled by the Board of Directors. The Board themselves, are controlled by the shareholders. The shareholders are controlled by the whims and fancies of the market, and at other times by the opulence exhibited by other shareholders.
Mothers-in-law and daughters-in-law wonder who exerts more control, while the men of the family think they are in control. What they often control is only the twirl of their moustaches! And the kids? Surely the kids are controlled by the parents no? Spend enough time with a young brat and you will quickly see where the control centre lies. But they too are controlled by schools, exams, the rat race, and life in general.
All in all, the external cannot be controlled. Hence the need to look internal.
