That's basically my approach, too, Berry!
I was reading in a (hard) journal today that back in 2017 I hit over 120 days without counting them, by just living life- being careful not to set oneself up for a fall. I also noticed how 'black-and-white' or perfectionist my thinking was back then, too, though. This would explain why I had to rejoin RN back in Nov of 2020.
But yeah, now I'm all about just finding that sweet spot of non-obsession, or just living life. I also have an approach of 'radical acceptance' (coupled with 'radical grace'), where even if I do obsess, act out, or even lapse, that it's not 'game over', not a restart, not a 'day-0', but just to get up, learn all I can from my lapse (what led up to it, how was I feeling, what stressors were involved, how was I loose with external stimuli), and just go on.
I simply mark down in a hard journal the date of my last lapse (categorized for me as P, PMO, or MO), and then just go on. Of course I can look back and see how much time I'm putting in between lapses, or note if I'm having a particularly rough month, or whatever.
The point for me now, brother, is to make deeper changes and not be as focused on the day count. Sure, it may reflect my efforts at purity, but is not necessarily a true representation of the inner changes that need to occur.
P.S. I love that reference to the Scottish pastor, and looking at Christ 10x for every look at self. And of course Corrie Ten Boom said:
"Look without and be distressed, look within and be depressed, look to Christ and be at rest."
