Personally I don't think one's 30K goals need to be integrated into a project list and next actions system.
What I do is have my 30K upwards goals/areas of focus in my weekly journal, which is separate from my GTD system. I review that weekly(ish) and just reflect on how my life is against those AoF or goals. Then if anything that looks like a project or next action comes occurs to me I just make a note for my inbox and then process it at the weekly review, or whenever.
Because I have always used computer list managers, thinking about 30K+ issues just doesn't seem right. They need a bit more of a relaxed reflective environment to work I think.
