I just created another topic for these kinds of ‘shifts’ in one’s practice-biography. E.g. for the things we feel we have wasted time on due to a misleading interpretation or being too concept-driven etc. I don’t know if this can become the sort of collection I have in mind, but I’d invite eg @frankk and @Viveka to briefly present their findings/experiences.
I guess repeating old points in detail is not necessary, we can easily refer to other posts per hyperlinks to not make it lengthy.
