Good post Mac and the only one I'd disagree with is Architecture. Whilst we joke that an architect is an engineer with their brain removed, nothing bigger than a single storey house would get built without an architect. All the magnificent buildings, ancient and modern, you see around the world were conceived by an architect
Over here, the architect is the lead in the proffesional team (designers, services engineers, structural engineers, etc), is the contact with the end client, interpreting their "vision" for the build, and instructing the construction company.
May not be the best paying job in the world (unless you're right at the top), and your patience and people skills need to be sound, but I imagine it must be pretty satisfying....... providing you don't mind having your brain removed
