Yeah I would agree with that. You can get into a mindset where you are extremely determined etc, and this even on it's own can cause you to do well at temporarily staying away from PMO. But this willpower and determination is unlikely to last that long. It's very difficult to just constantly remain in that extremely determined mindset.
It's one weapon at your disposal. But willpower is a scarce resource, it is better to focus on creating the right environment where watching porn seems very unattractive and difficult.
I share the same view as yours. I also have started my own website about 9 months ago. It's quitfappinglivestrong.com, would it be interesting to you if we join forces and create a series of videos, and or blogs around the subject?
