Yes, big fan of Pressfield's work too! Wish I encountered him soner. I think one of his best points is that you can practically "navigate BY resistance" – acknowledging, addressing and leaning into it.
Oh yeah, good point. As Pressfield would put it, the important thing is to go Pro. And a Pro would finish the job that he started, even if it might not be "worth doing". Unless you're literally risking your life or something improbable like that, it's worth finishing what you start.
