Why is it that we always want what we can't have??

because that is human nature to always want more and stuff we cant have. the trick is how to learn to be content with the stuff you have.

It's human nature, not satisfied with what they own. Always wanting more, and always looking for that has not owned.

I know what you mean. There is always the desire to have something that is just out of reach. I would like to think of it as ambition but I think a person has to make it that. I have also seen people work very hard for a goal and then reach it only to remain unsatisfied and decide that something else would be better. I think that there is nothing wrong with setting goals but I also think that we should try to be happier with the things that we are able to accomplish.

Good question. We have evolved to 'want', it served our ancestors well when times were tough, and they had to hunt for food. However it becomes 'maladaptive' when you put the same (in evolutionary terms we are of similar makeup to our hunter gatherer ancestors) brain pathway (it is a pathway stretching from the ventral tegmental area, shooting up to the nucleus accumbens area of the brain (incidently, it is this pathway which plays a role in addiction too) in say tesco where food sources are abundant (hence obesity) or in a capitalist society whereby choices are abundant. One is therefore inclined to want for everything, as a result becoming unhappy/depressed - which then makes pharmaceutical companys money. Its all to the profit of big business. Lady's and gentlemen this is the exploitation of humans for profit - known as 'advanced capatilism'.
