Is my desire my downfall because I believe it is mine alone?

To be in perpetual conflict with the world that is around us is a philosophy that many have explored. Is it fair to say that each and every one of our desires are driven by an interaction with the external - be it conscious or not?
True, to believe we can find inspiration within without the elements of our external environment would be naive, even when the environment within and without no longer make sense. Subconsciously they are inseparable. What's within is shaped by the external and our interpretation of that external environment is a personal one shaped by what is within. If they don't make sense it's often because we're faced with the unknown, something our internal self has yet to experience through external happenings, and has yet to imagine through internal conscience.
However, to return to the original question of how our internal conscience and desire is fed by the external, our uniqueness must also be considered. Indeed, we may feed off each others desires but our manifestations of these will always be unique.

My uniqueness is mine, so why question it?

We're all unique and yet there exist a plethora of frameworks and tools which seek to identify our personalities. Surely this profiling is doomed to fail at the first hurdle, indeed how can I be categorised if I am me and no one else? I accept that certain personality traits can be more or less prevalent in each individual, and I'll be the first to admit that to date, my personality "type" has always been spot on (for the record I'm an idealist with an artistic streak). What I have difficulty with is the idea that we are born into our personalities, that our character is set in stone relatively early in our childhood. Surely our exposure to people, places and experiences, our interaction with these and our ability to increasingly live in multidimensional realities stretches our persona to the limits of existential psychoanalysis

Equity vs. Equality

Because we are living in a society where we have access to the same resources, does this make us as individuals equal? Or more to the point can we claim to live in an equitable society? Indeed, one persons position in an equal society can be a symbol of another's failure. Because I earn less than you, am I less successful? Because I come from a privileged background, is my success any less worthy?
The debate is even more poignant when opened up to health care. Indeed, in the UK we can almost speak of an equal and equitable health care system, until that is we cross the line into drugs pricing. While in the US, the equality on which the nation is built is a far distance from achieving equity in health care provision.
