Because we have made a pact with life to be born, to exist, to smile and to weep, with the burden of seeing it through 'till the end.
Because we're human, and to be human is to give a damn about the world that is made and unmade around us.
Because the flames of progress are burning, forever, and nobody wants to be there when the fuel runs out.
Because we're beings, you and I, borrowing from physical space and interacting with infinite beauty.
Because the meaning you seek manifests itself in the trees swaying in the winds of spring.
Because nothing worth doing is ever easy enough to overlook.
Because you live on, anchored to wills of tempered steel.
Because the soul demands it so!
After all... why not?
