Roots: a meaningful mixed-up metaphor
These roots (mixing metaphors big time; Urban Dictionary kind of ruined that Texas expression), these roots make you what you are. The things that got you started are always good to return to, especially when you're lost. This is where the deep well of meaningful but murky stuff resides- all the youthful energy, all the dark yearnings, all the conflict, family demons, love, hope, etc. That's what roots do- suck up deep unformed things and give them visible shape. This doesn't mean you have to spend your days ruminating over Woody Guthrie, or Shakespeare, or Nirvana, or Cormac McCarthy, or Kendrick Lamar, or whoever got you going in the first place. Return, get your bearings, and then head out for new work.
