As for forever....it has been posted here by RobbyRobot, whom I greatly respect, that you simply cannot fathom "forever" in the beginning. That is so very true. You can set your big plan and start using AVRT, but the ability to truely accept forever will come. The first phase is to start recognizing the AV and learning to deal / cope with it.
Make the plan. Share it with a family member, or friend if necessary so that you have some skin in the game. From the sounds of it you do not accept failure easily. I certainly do not, and it took this step for me to get started in earnest. "I cannot fail in their eyes" sort of thing. It is not necessary, but I needed that little crutch to get started. YMMV.
