I know this isn't a "mutual self help" forum and you are not liable - I would just like a light hearted survey of a few ideas that might suit, and it doesn't matter if not. A lot of us have probably been there, as we approach mid life or whenever.

For a bloke that spent many years in an intense and highly charged movement, swearing vows every three weeks. He has dropped out of it some years since. But he has to stop re-re-examining the details. A certain amount of testimony was borne but seemed to meet with an ambiguous "response". All authorities that were formerly involved now have to be seen as a "dead end". The man concerned has a talent for thinking analytically which he is developing. But he has to filter out this memory which is no longer relevant.

Hence how to bracket - very definitely - this whole set of associations and go on figuring out, ever more clearly, thereal issues in life from now on. Then he can stop spiralling. He can become the individual he is destined.

Any light-hearted "informational" ideas? Something to be repeated daily, is probably acceptable. Only it has to be respectful of continued intellectual effort, overall.
