You cannot force anybody to use GTD.
I think you cannot force anybody to use GTD and I am afraid that you are trying too hard to "encourage" your coworkers. Just show them your extraordinary results.

Yes, just chiming in on the general consensus here... Wondering whether they really resent your organization, or whether they resent your "advice." Most people will only hear any message when they're ready to hear it. So the best thing anyone can do is to model being really organized, and pretty soon the people will be coming to you and ASKING what you're doing that is obviously getting you such great results! In short, you let them come to you - like "The GTD Whisperer"!!
