I disagree, window licker... We are told by society to strive for our happiness, and classical philosophy (on which our modern ideals and political systems are based) states this as our mission. But we are always striving, there are always goals to achieve. 99% of the people you ask will tell you they're not where they want to be, yet.
I think it's when people blind themselves to truth and meaning, and become numb with social anesthetics, that misery and pain are inevitable. People tend to want to keep their minds busy with the day to day hustle toward some end...happiness, I guess... and avoid looking at what this world really offers us.
Is this reality? A great question that we shouldn't be afraid to ponder.
