It would seem to me, at a brief look, that you have mistaken the idea of "projects".

Education/Finance/Work etc. are not projects. They shall be considered, more GTD-appropriately, as areas of responsibility.

Projects are anything that requires 2 or more next actions (***physical actions - I tend to define them as the single set of action that I can perform in the same space & time ***). Projects have /i a purpose or vision /ii a desired outcome (how it physically look like if it's a WILD SUCCESS); with these two you go onto project planning with 1.brainstorming 2.Organize ideas 3.define next actions.

Now, for example, let's look at the "finance" project. What is the purpose/vision? You could say it is to "surpass Bill Gates on my account net worth", or other kinds of whatever you think of. Now that you imagine a wild success to align your intuition with it, then go on to the later phases of project planning....
While this may also work, it makes more sense to me to break this giant 'project' into more realistic ones, like 'obtain $2 million real estate profit in 1 year'. Now you can define the purpose/vision & principles, imagine wild success, and go onto the other phases.
