Corporate Ladder in the Black Hole

What happens to people when they grow up the organizational ladder or in the society? What should they do to sustain and keep going up? The modern day mantra across the world for addressing the above questions lies not in psychology or management, but in physics! You would have heard of an astronomical entity called Black Hole (well, you would have if you have seen the movie Interstellar). Black holes were once stellar bodies that started collapsing into itself thus gathering extreme mass and gravitation, till they reach a point where they pull everything into themselves and does not let anything, including light, escape from it. Hence the name. Likewise, as a person grows up the corporate ladder or even in life, if the craze for power gets to them and they want to stay on top and keep growing, then they should start becoming self-centered, ensuring their own gains in everything by hook or crook, and never let anyone else surpass them. They will have to become the center point in everything, no matter if they deserve to be there or not. Such people will surely succeed. Of course other people don't call such people as Black Holes, but something more or less similar in rhyming though. Bah, who cares?!
