Nobodies mentioned the dichotomy paradox yet?!

Little jhonny is about to leave school and head home.

However before little jhonny can get to his house, he must get half way to his house.

But before he can get half way he must get half way to that point.

The preceding series continues on and on until you must ask, if you can always devide a distance in half, how is it possible for little jhonny to move the first distance towards his house?
