"Discover your own discontent, and be grateful, for without divine discontent there would be no creative force." Deepak Chopra
I am perpetually dissatisfied. I always have been. That doesn't necessarily mean I am unhappy, it just means that I usually can see a way for things to change.
Such dissatisfaction could be seen as a flaw—it might seem that I am always the critic, finding fault with everything: it can also be seen as a path towards change and even transformation.
I recognize that discontent in large doses is hard to be around—it can sound very much like complaining or even worse—like whining. But beneath this discontent is a drive towards change, a desire to make things better. It is a sense of the possibility of things, and when acted upon it can be the impetus for creativity and freedom.
