Troll confirmed :P there's an extra door too many, it is literally impossible, if you take away one door from the outside or the one connecting the two top boxes it can be done but otherwise impossible.
You can't win, because no matter which room you start in, every other room has to have an even number of doors so that you can enter and exit and not get stuck, or leave a door unused. This is not true in this plan, therefore impossible.

Troll confirmed :P there's an extra door too many, it is literally impossible, if you take away one door from the outside ... it can be done but otherwise impossible.
Specifically you'd have to take away the door between the outside and the bottom middle room, because you either need every room to have an even number of doors, or exactly 2 rooms with an odd number of doors, where the outside counts as a room as well.

You can prove that it's impossible:
If a room has an even number of doors, then the line doesn't have to start or end in that room. (It can always enter through one door and exit through another.)
If a room has an odd number of doors, then the line has to start or end in that room. (Easy case with one door: Exit through that door. Next case with three doors: Exit through one door, then simply pass through the other two like if the room has an even number of doors.)
But three rooms have an odd number of doors (top left, top right, bottom center), and no line has three ends.
(Edit: Totally missed The2DollarHooker's post. Yeah, what he said.)
