Flow at work refers to a short-term peak experience that is characterized by absorption, work enjoyment, and intrinsic work motivation, and is positively related to various indicators of job performance. In an organizational context, research has predominantly focused on situational predictors of flow -including challenge job demands and resources. In this article, we propose that workers may also proactively create their own optimal experiences. We use self-determination theory to argue that all human beings have basic needs for autonomy, competence, and relatedness, as well as an inherent tendency towards proactivity and growth. We propose that workers may use four self-determination strategies to satisfy their basic needs, facilitate flow experiences, and, in turn, increase their job performance: self-leadership, job crafting, designing work to be playful, and strengths use. Furthermore, we argue that factors within the organizational context -such as human resource practices and leadership, as well as personal resources -such as self-efficacy and optimism, moderate the effectiveness of these strategies. Implications for theory, research, and practice are discussed.
