To be Human is to want

It seems that it is human nature to want, to have desires, to yearn for things. Freud says "We think that we could be happier if our every whim was satisfied...that idea of continual sense gratification seems a delusion.Our desires are insatiable, for as soon as one is satisfied , another takes its place. Part of the secret of happiness is to learn to be content with what one has, not to seek for more than life can offer." I agree with this statement from the "Who Are We" text (pg 178). The more things we want and the more things we get is the unhappier we will be. Desires/ ants aren't easy to get rid of because whenever you do get what you "really want" you will see (desire) something you "really really want." It seems that in this day and age people are hardly satisfied with their necessities and must have the things that they want in order to survive. Why is that though? Why is it so hard to not want anything? Is it because we live in a complex world where having something makes you "better" than the other person? Is life an on going never ever ending competition of I have this now I am better than my neighbor, then the neighbor sees it and desires it? Do not look for or try to gain things that is not necessary for survival if it means you being really unhappy and missing out on life until you get it. It is going to be a never ending cycle, and then guess what.....you die. Then when you die what happens to your 5 houses and 8 cars, it gets donated, given away or if your very possessive buried with you? All the things that you desire and working yourself up for and being unhappy about is going to be here after you die, so why kill yourself trying to gain material stuff and miss out on living? I don't think I will ever understand.
