Satisfaction VS Contentment

In the dictionary contentment is satisfaction and satisfaction is contentment; they are synonymous. But in life it is not so: they are diametrically opposite. Coming from the quote: "Until you make peace with who you are… you’ll never be content with what you have”. So no matter how much you are earning you will not be contented because of who you are. Although you feel satisfies but you wanting more because you are not contented.
