I love GTD. It gives me a full overview of my commitments and goals. With GTD I was always strugling to go through DOING phase. So decided to test something new like Autofocus version 1. It looks like it doesn't care about systematization aspect and focuses on doing. It lacks Calendar, Tickler, @Agenda and @Waiting though.
Since you are a Connect member, did you see the "Procrastination" webinar? If not, I highly recommend it. You can find the link to in from the home page, in the archives.
