I still find the way one moves a saber oddly more comfortable. But the interesting thing was, after I spent some time parrying in saber? When I went back to foil, I understood how it worked a little better, too.
My first (internal) reaction to changing weapons was “No, no, not something new when I still have so much to learn!” But sometimes we need to switch to learning something new–for its own sake, and for the perspective it gives us on what we already know, too.
Which I’m sure is relevant to writing and comfort zones, too. If you just keep using the tools you know how to use and writing in the ways you know how to write, you can only go so far with what you know. There’s a certain–control?–you can’t get without outside perspectives, and with the flexibility of being able to do more than one thing if you choose.
It’s easy to forget this, especially when the what-we-know seems tenuous to begin with. But maybe it’s best to never get to stay in a comfort zone quite as long as one likes, and to stretch before one quite feels ready.
