This article reports on an intervention based on a new approach to career counselling in the Anthropocene era. The research aimed to examine the determinants of the changes that occurred in the research participant rather than just the changes themselves. A gifted 17-year-old male (clarifying his career choice) was conveniently and purposively selected from enrichment workshop attendees. A descriptive and instrumental case study research was used to generate data. The workshop attendees completed the Career Interest Profile and the Maree Career Matrix to facilitate the intervention. Savickas' guidelines for analysing career construction-related data were used to analyse the data. The intervention enhanced the participant's psychological self as an autobiographical author especially. After the intervention the participant gave evidence of an enhanced sense of eco-awareness and moral behaviour). Further research is needed to establish the short-term and long-term effect of the kind of intervention in individual and group contexts.
