Think about how much staying off porn will help you.
Porn ****s up your mind. You know who's a big porn addict? Ted Bundy, one of the worst humans in history. And yes, he blames his actions on his addiction to porn. He also points to porn as the cause for most of his immates' crimes.
I'm not saying you'll become a serial killer, but it is obvious that every second of soft and hardcore porn you expose yourself to, the more your brain is being
irreversibly damaged.
Think about this right now. Not later when you're about to click on those movies. It is useless to try to convince yourself that porn is bad right when the urge comes. you must convince yourself of its effects on your life when the urge is not there. Then you will be able to have better control of yourself. The urge will eventually come again, but your impulses will be a little more controlled each time if you keep in mind the rest of your time what is best for your psycological and spiritual welfare.
Here's a link to Ted Bundy's interview where he gets right to the point

If you really want to stop you will watch that interview. That should do the trick in convincing you to watching stop porn.
