I guess "Relentlessly Resourceful" is the same thing as "Get sh*t done".
(PGs 'being an animal' is the internal version, while GSD is external.)
I'm not sure it can be taught, after the age of five.
In my experience, it can be latent or simply turned off, usually by social norms [or schooling]. I've seen two cases where people really took off when they were simply given permission to 'GSD'. We managed to bypass a lot of organizational crud by effectively building a startup within a parent company, that was largely independent for the course of the project.
We used guerrilla tactics like stealing, ahem 'co-opting', people who we thought might be good if given a chance. I cringe to admit it, but we also used the unfortunate but necessary contrapositive of inventing nul sub-projects to keep non GSD people busy - those whom we had to have on board for political reasons, but who chose to basically just clock hours - so they wouldn't kill off other good work being done.
I guess in a startup, you publicly give yourselves permission to GSD [the whole S, and nothing but the S! :]
