You have broken into Contraplexus headquarters, a secret organization bent on destroying all puzzles in the world, with the task of procuring the latest research they have developed in another room.

Most of the building is one large room with several desks, and to the north is the door leading into the next room.

My method for solving this problem involved working backwards.  Pretend you start at the end of the problem and that the desks and walls are "bumpers" that you can chose to hit you from the side to change your direction.  Also realize that you HAVE to choose to get "bumped" into a new direction eventually, and are not allowed to instead just run into a wall, because when working backwards you can't push yourself; if you run into a wall you're stuck.
There are a lot fewer options this way; you HAVE to get pushed east to begin with and then south and then west because those are the only "bumpers" available, and usually when there are two or more options one of them is immediately obvious as a dud (in the next length following the ones mentioned, for instance, you have to choose the first bumper to bump you south because the second one bumps you south then west then north with no other options and you're stuck.)
