Yeah, I've started to do a similar thing. I tell myself that I'm not the kind of person who watches porn when I feel a strong urge. It makes sense to me because the idea of "quitting porn" brings along ideas of struggle and relapse and it's easier to find excuses with that mindset. An identity shift is more resilient. Maybe it's a bit like the "Do or do not. There is no try." wisdom from our favourite green alien.
