Any ideas?

So i had a method that strengthned my will during times where i wasnt feeling urges. I wrote down what my life would be like with and without porn in a couple of years. And then i wrote down the fact that im good and was born good (because if you dont believe you are good then you wont be able to sacrifice for your own benefit, meaning being able to stand in and feel the urge without giving in to it.) This method works! But it takes 30 min to do it. Its too much for me to keep being consistant with it. I am not sure what to write down to shorten it either. Is the loving myself part the most important thing? Or the knowing the future consiquences important? Or the dream of what my life could be without it? Im not sure what to kick out and what to leave in. So i need your guys help. Type what you would write down everyday to strengthn your will to kick this habbit and ill write it down everyday. Something short and sweet that wont make it seem like homework when it comes time for me to put in the work.
