That kind of sounds like a line out of a Star Wars flick, or maybe Dune. The Resistance being some kind of rebel warriors worth fighting for, or against.
I'm talking about a different Resistance. I've just finished Steven Pressfield's "The War of Art". I read two important books this past year and this was one of them. (I read a number of unimportant books as well.)
Pressfield is a well read author, mostly military novels as well as "The Legend of Bagger Vance", which became a movie. The War of Art isn't one of his novels... it's a book for writers and artists about how to get down to business and produce their art. It's lesson's he learned about being a writer, while he was working on his novels.
The Resistance is that force against all of us, that stops us from doing what we should be doing. It could be as simple as constantly checking email, to watching a movie trailer or creating busy work, while we should be creating art.
How well we fight the "Resistance" is reflected in how well we finish our art. And art can be anything, from a photo project, to making a wooden boat.
