i think there are four factors that influence the life quality---work,family,health and how u spend ur leisure time.
for most of us ,work is the central,dominating factor of life.we spend most of our concious hours at work.what we do there largely detemines our standard of living and the status we are accorded by our fellow citizens.
family is the place where we have true love there.our relatives alawys stand by u and nomatter what u r in the workplace or social circle,they love and cherish u at home. that feeling will make u happy and centented.
also, the health and leisure time are the foundations
i prefer the integrity man use the convicing law to gover the world.
