Solution? Hire someone hard-working and curious, who has a natural proclivity toward organization, and teach her/him GTD.
My first boss out of college (a personal assistant job) had bought a copy of GTD for everyone in our company (13 people). He told me about it in my job interview, and gave me a copy on the first day of work. I had a ridiculously slow computer, and so I read an entry or two from
Ready for Anything every morning while I waited for that dinosaur to boot.
I have not worked a day of my adult life, save the first week when I was reading the book, without knowledge of the GTD principles and system. It fit my worldview already, and yes I've had to tweak it for different situations, and now I'm in academe, which is a whole different kettle of fish, but it has always been the core of my functioning in the workplace. If you hire the right person, she'll take to GTD like a fish to water.
However, I agree with Eureka's comment, however tongue-in-cheek it may have been intended--people who gravitate toward GTD tend to rise fast.
Our business manager took another position eleven months after I was hired, and so I took over her job instead of staying the assistant.
