" I know I want and do not have what I want. A weight hangs suspended from a hook; being suspended, it suffers because it cannot fall: it cannot get off the hook, for insofar as it is weight it suspends, and as long as it suspends it depends.
[...]
Its life is this want of life. If it no longer wanted but were finished, perfect, if it possessed its own self, it would have ended its existence. At that point, as its own impediment to possessing life, the weight would not depend on what is external as much as on its own self, in that it is not given the means to be satisfied. The weight can never be persuaded.
Nor is any life ever satisfied to live in any present, for insofar as it is life it continues, and it continues into the future to the degree that it lacks life. If it were to possess itself completely here and now and be in want of nothing—if it awaited nothing in the future—it would not continue: it would cease to be life.
So many things attract us in the future, but in vain do we want to possess them in the present. "
