In the spirit of "-10x is dragging everyone else down" I offer my take on +10x:

It's not about personal productivity. It's about the collective productivity that comes from developing and implementing processes that take advantage of all levels of skill, from neophyte to master, in ways that foster the growth of others, both in skill and in their ability to mentor, guide, and foster the growth of others. The ultimate goal is the "creation" of more masters and "multipliers" while making room for those whose aptitudes, desires, and ambitions differ from your own.
