That's a fine piece. I like the suggestion that data collection and self-monitoring during the early months of maintenance will allow "relaxed practice" later and a more peaceful approach to maintenance.
But it is my observation that those who succeed in maintenance long term are the ones who have learned to relax into the practice. White knuckling through something can get you over the hump in the short term...but it is unlikely to provide a long term success. And when you do let yourself slip, all that built up tension is likely to lead to a monumental fall.
And her remark in a comment:
I see early maintenance as a time to collect this information about yourself and later maintenance as a time when what you've learned becomes second nature. It's no longer necessary to concentrate on it, because you already know the outcomes.
As with all other advice, don't use this method if you find it doesn't work for you or does't fit with your beliefs.
