do not have stable object level solutions.

As I said; <making advice applicable> is a viable strategy, and as a step in the process; understanding why advice is applicable; can help you in applying it.

Example: advice - spend less time organising and just get down to it, (was offered to me by a student who was borderline OCD, enjoyed the scheduling side of things).

I looked at this advice and realised it is really great advice (for herself, or others in her position,) for people who spend too much time organising, but entirely not helpful for myself who spends zero (+/-) time organising myself. By understanding the reason why; (as you said), "a method that worked for someone... to reach a local optimum." you can better plan and try to apply solutions to your own situation. (I appear to be strongly agreeing with you)
