I'm in an interesting position--it's entirely possible that I could finish the list before the release of the next edition, which promises to hold 50 new films in recognition of this being the 10th edition. I've decided in the past that I'll leave at least one film (The Last Picture Show at the very least) until the new volume comes out. Were it not for that, I likely would finish before September 30. As it stands, that date will likely push back to late November or early December.
Most important to me, the goal I ultimately settled on was finishing in four years. Even with the continual addition of new films (I think I started at like 1056 and have seen that balloon up to 1103, and potentially 1153 this year), I'll still make it barring any serious trauma. It's a good reminder that such goals are achievable, provided that one works toward them consistently and maintains a level of focus. I realize I now sound like a moral from the G.I. Joe cartoon (and knowing is half the battle), but it's true in this case.
