It has been said that if you are o.k. with the world then you are not paying attention. While your thesis is true, there remains much work still to be done.
I agree that we shouldn’t worry to the point of exasperation, futility and despondency. At the same time we shouldn’t pull a muscle patting ourselves on the back.
