The Price of Immortality

What is the price of immortality?!
Immortality has always been my most mental involvement. In fact, I think whatever happens I would like to be immortal in the History's mind. I have thought and talked about this issue to my spouse for many times in order to distinguish a practical plan to remain immortal! Writing, I think, can be one of the best plans for this desire.
But today, my spouse raised an issue which intimidated me! He was talking about people who when think deeply, they conclude that if they were not in this especial positions, nothing would be happened. Being or not being would not be an issue indeed!If one of them didn't do something, there is another one to do that. Right?
I criticized him so much because I was afraid of this explanation. I told him this way of thinking eventuates in the holocost and some other human disasters! He responded I was wrong because his purpose is when somebody "hirself" think in this way and think "others" are more important than "hir" and they are not as impressive as others in the society.
I told him I can see what you mean but "you", as the analysist are definitely dangerous! If a social analysist thinks in this way that most people are not sufficiently beneficial for the society, there will be many many human disaters! All impressions to other people is permitted by this style of thinking that really all people are not as important as others for human kind society! This style of thinking if does not entail horrible disasters, at least entail every kinds of discriminations; racism, sexism and others.
Suddenly, a thought was came out to my mind. What is really the price of immortality? Why when we read the best and most impressive people in human History, they have not been as successful in their personal life as in their career?! Have the price been the victimization their families and friends? Is it really right?
Maybe I should read more and then contemplate more on their personal life. It is really important to me that what is the price of immortality for my family, friends, kids and spouse? If I bother them and indeed victimize them to achieve my goal, is it really fair? Maybe it is fare for human kind and the future in general and unfair for the present people around me.
I think about it more profoundly and I will try to find a rational, logical and FAIR answer for myself; fair for my family and actually fair for myself. It is another significant point!
Am I ready to pay this price for immortality? I am not sure indeed!
