This booklet consists of some papers on the Trajectory Equifinality Approach (TEA). These papers have appeared in journals and book chapters for more than the past decade. From them, readers can understand how TEA itself has transformed over the years. Although readers might get confused, this transformation indicates further transformation may occur in the future, and I sincerely hope that new readers promote such a future-oriented transformation of TEA. TEA is a kind of frame-game, like Linux. Therefore, you can use it with no permission with reference and create new ideas on TEA.

The Trajectory Equifinality Approach (TEA) has a definite birthday: January 25, 2004. About a decade ago, I welcomed Jaan Valsiner of Clark University, USA (now of Aalborg University in Denmark) as an invited professor of Ritsumeikan University, Kyoto, Japan, where we held a symposium on cultural psychology. I presented my research on pocket money using a basic idea of equifinality in developmental phenomena, after Valsiner (2001b, 2003a). Immediately following this symposium, Professor Valsiner proposed that I write a chapter on TEM. He then decided to transform the symposium on cultural psychology at Beijing, and a presentation concerning TEM was given on the psychology stage on August 12, 2004 (Sato, Yasuda et al., 2004).

Ten years after the first chapter on TEA was written (Valsiner & Sato, 2006), the first English language book on TEA, Making the future (Sato et al., 2016), appeared. Colleagues from different countries (i.e., Colombia, Estonia, Denmark, and Switzerland) contributed to the book. I am thrilled that TEA has become a common “methodology” used worldwide in cultural psychology. I am also glad this booklet (of collected papers) will help researchers who have an interest in describing the process of human life course.

Papers collected within this booklet have their own history. Many people have made direct and indirect contributions to the papers collected herein. I am deeply grateful to all my coauthors. Without their ideas, inspiration, and support, this booklet may have never appeared.
