You'd reach it, even theoretically, you're already THERE the
  moment you envision the goal.

  You're conceptually in TWO places at once: One at the goal line,
  the other traveling TOWARDS the goal line.

  So even theoretically, just to be able to STATE the goal,
  imagine it, mathematize it - you already have it and you're
  already THERE.

  There's no paradox.

  One of the limitations of mathematics, honestly; the inability
  to see itself.
