The first ninety day challenge failed because he did it alone, and Mark Anthony Irwin says so at the start of the second one. That admission is the most useful sentence on the blog. He had assumed that discipline plus hope would be enough, discovered that nobody was going to notice whether he showed up, and joined a group the second time round.
The post that follows is about appreciating what you already have, which he took from an audio recording rather than inventing, and about how gratitude functions as a way of moving rather than a way of settling.
The other post is a different business entirely. Writing from Freiburg, he introduces a form of energy healing practised at a distance, cites the authors who have endorsed it, and offers a first session. Nothing in it is evidenced, so read it as an advertisement, because that is what it is.
Two posts, pulling in opposite directions. The challenge one is honest and short and worth the five minutes.
