Was reading qihui blog on this question haha, well different people will have different poin of view... manling also blog about her view on the this topic being questioned out by qihui in his blog :X

Well, this i how i feel about sense of satisfaction:

Doesn't mean people achieve their wants will giv them satisfactory, wat about poor people? Poor people also have needs and satisfactory to them is when they meet their needs, they will be contented..there are also alot of poor people in the world..their heart tells them about wat they needs and wants main are for those people who can afford their wants within their limits..

Most people are nt rich and there are more POOR people then Average capablility people in achieving ther lvl of satisfactory also..there different in the satisfactory of the POOR and the rich are too far..so i think both needs and wants are required..People usually wun be happy after achieving their wants.. but to the poor, once they achieve the needs that they needed, they will feel glad and contented, unlike those people who have average income to afford their wants and they will still be nt satisfactory after getting what they want... coz they will simply want more as new technology and stuff will be created after the original version.. Dream will nt bring satisfactory to people though as they will change their mindset as times goes by as the dream maybe is nt really wat they want and they find a new dream along the way as they grown up.

Usually to poor people, they will be content and happy with a happy family and the needs that they needed...but for the rest of the people who are not poor, most of the time they will not be contented and happy after buying the things they want as there will be better stuff coming up or newer version/designs of the stuff...and when that times come, they will want to buy these new stuffs again...

Agreed with Manling about this paragraph from her post:

"life is an irony isnt it?? when we wanna show concern to people, end up hurting them. when we wanna love them, end up hating them. when we wanna do well for exams, end up screwing it up. when we put in so much effort, our efforts will go down the drain~~ when we had high expections, we fall right to the bottom.. and hurt ourselves badly. when we try to pick ourselves up, we meet obstacles again~~"
