  Harnessing the sheer discovery potential of gravitational wave astronomy will
require bold, deliberate, and sustained efforts to train and develop the
requisite workforce. The next decade requires a strategic plan to build -- from
the ground up -- a robust, open, and well-connected gravitational wave
astronomy community with deep participation from traditional astronomers,
physicists, data scientists, and instrumentalists. This basic infrastructure is
sorely needed as an enabling foundation for research. We outline a set of
recommendations for funding agencies, universities, and professional societies
to help build a thriving, diverse, and inclusive new field.
