You seek so that you can keep on seeking. What separates this from seeking the seeking? The only true striving is that which aims at an attainable goal. If your goal is unattainable whether you know or admit this to yourself or not, the striving will only return you to itself. Perhaps it shows you something else as well, as when your goal is attainable, but only not by you. And you claim the impossible as more noble than anything possible meaning that you have not yet begun to seek it in earnest.
