I went back to being a beginner at 68.

Then I wrote about what that costs and what it returns. I research business psychology at École Internationale Universelle in Paris, and I write trade books on Buddhist thought and working life.

Most of my work asks one question in different forms. Why do capable people keep scaling something that was already enough?

Research

Single-authored work in business psychology, written from Bangkok and affiliated with EIU Paris, most of it built on data I could actually get my hands on rather than the data I wished existed. Two further articles appeared in Scopus-indexed journals in 2025, co-authored.

Where a paper is still in review, it says so.

About

I spent most of my working life in Thai industry, close enough to the floor to watch capable managers repeat the same expensive mistake for years without anyone ever telling them it was one. I am now a researcher in business psychology at École Internationale Universelle in Paris, and a Fellow of the Royal Society of Arts.

What I keep returning to is the gap between what a person can measure and what a person can actually judge. Managers certain they delegated well. Founders who scaled past the point where scale helped. Writers who mistake output for progress. The work is not about slowing down for its own sake. It is about noticing where the returns stopped.

I write in English and in Thai. Everything now goes out under my own name.

Speaking and correspondence

I take a small number of talks each year, in English or Thai, on sufficiency, delegation and the psychology of scale. For invitations, review copies or research correspondence, write to me directly.
