As there is the notion of positive and negative space in the visual arts, sculpture and architecture as well as music, one can look at life’s problems, roadblocks, obstacles using the trope of positive/negative space. Instead of grappling with a perceived problem or person as a discreet object, look at the variety of space that abuts it, surrounds it - select a zone of abutting space for your attack, pursuit or attention. All matter is defined by its context. As you change one aspect of the context you are changing the nature of the original object / solid and as it changes you may find the new thing more accessible to your skills and pursuits.
