Doctoral education presents significant challenges, often leading to high dropout rates and extended completion periods. This paper examines the case of a PhD candidate who successfully completed their doctoral studies within three years while maintaining full-time employment and without financial support from funding agencies. By considering the candidate’s and supervisors’ perspectives, this study explores the obstacles encountered and the key factors that facilitated the outcome. Findings highlight the role of structured supervision, timely and constructive feedback, academic engagement, and the ability to balance professional and research responsibilities. Additionally, the study underscores the importance of fostering autonomy and motivation through good mood and proactive and supportive supervision. The insights contribute to the broader discourse on effective research training and doctoral program design, offering practical recommendations for enhancing supervisory practices, student preparation, and institutional support systems in higher education.
