Raju,

Everyone is selfish, its just a matter of how much. As the world grows bigger and more populous, people grow lonelier, feel alienated. There is this thing called the butterfly effect, and I believe in it wholeheartedly. A small insignificant thing CAN and WILL lead to a chain of reactions producing something incomprehensibly massive.

But blinded by our own selfishness, we don't usually foresee the ripple effect of our decisions on others.

It is a sad fact that we gotta fit ourselves into this already carved up model of the world. And being "free" is really just another utopian dream.

Which brings me to my main purpose for this comment. As Mr. Hyde aptly put it,  "[You gotta] find  [your] own calling or purpose in life." The 'demanding' people you talk about are just that. Very demanding, very egoistic, thinks all other lifeform is inferior to them, abhors failure, and are very good at using people for their purposes.

Now is when you have got to see the doughnut and not the hole. Those kinds of folks think everyone is like them, but truly, only make up a small percentage of the people. Dont make the mistake of assuming everyone out there is shrewd and demanding and 'chandaal' and what not. But dont be too naive not to know one when you see him/her ;) Usually if you follow your intuitions, it will give you subtle warning signs.

Life is short, but full of decisions. The game is about making the right ones :)
