contentment is ambiguous... whilst it may be preached in many ways, my Personal Belief is that it can be both Good or Bad depending on your age, the stage of life u're at, the country u're born in and the dreams u hold... amongst many other factors, so Application of this word goes to the formative ingredients behind the footprints we make in life.
in spore, being contented to the point of suppressing One's own fair ambitions, should not be what young adults or even adults in their 40s should adopt, least u have already done enough to sustain a steady pace to glide thru life fairly comfortable.
in a meritocrous society like ours, contentment can be carried on the lips of the fairly wealthy and successful, but not for those who struggle... becos Contentment is the fine line between Striving, or Giving Up too early, too easily...
if u are easily contented, the question should be self-explored, on whether it is becos u are very comfortable... or becos u have already given up on what u want in a self-defeated mindset.
