Justifying My Whole Existence

I'm forever in pursuit and I don't even know what I am chasing. . . And now in one hour's time, I will be out there again. I will raise my eyes and look down that corridor, with 10 lonely seconds to justify my whole existence.

Plagued by doubts...

I am plagued by doubts. What if everything is an illusion and nothing exists? In that case, I definitely paid too much for my apartment.
