Is it human nature to never be satisfied with our lives?
To always want bigger, better, more expensive things?
To long for what is outside our reach?
To compare ourselves to others and only see what we lack?

And yet, is this not what spurs us on?
To push ourselves to the limit and take ourselves beyond what is deemed to be our fate in the natural order of events?
Would mankind be this advanced if not for our hunger for more?
The answer to me is - no, we would not.

But then again, I am sure that there are people in this world who are perfectly happy with their lives though others may find it lacking in many ways.
