Appropriating Activity Theory #15: Before, After, and Watershed

[Case Study] When the Circle Changes the Center

It is presented here as a case study in Supportive Life Discovery (SLD) — specifically as an instance of the Achievement Chain in action.

A Chronicle of Revisiting–Rebuilding Practice (September 2025 – March 2026)

A Watershed of Creative Life

In A Chronicle of Revisiting–Rebuilding Practice (September 2025 – March 2026), a series of RR practices is organized around a single watershed: October 2018. December 2025 marks a new watershed in my creative life.

The World of Activity of Mid-life

Throughout the editing of this collection, I kept thinking about a project I had abandoned in 2024: the Mid-career Curation Program... Coming back to it now, through the lens of RR practice, I see it differently. This epilogue is that return.

The Landscape of Strategic Developmental Psychology (v1.2)

What was once a method for building sociology has now become the foundation for a new Strategic Developmental Psychology—a transition from understanding how we create culture to understanding how that creative identity, in turn, develops the self.

Revisiting and Rebuilding: A Strategy for Creative Identity Development (Possible Book, 2026)

The possible book is organized to reflect these three dimensions — temporal structure, creative strategy, and identity development — across six parts.
