Mental time travel lies at the frontier of research into motivational persistence in language learning (Dörnyei, 2020). This article introduces the theory of episodic future thinking (D'Argembeau, 2016(D'Argembeau, , 2020, and examines the key components of autobiographical knowledge and personally important goals. With findings on the long-term goals and career aspirations of preservice English teachers as a departure point (Erten, 2014;Ölmez Çağlar, 2019), I outline the contributions that episodic future thinking can make to the psychology of second language learning and teaching. Positioning episodic future thinking in conceptual terrain at the intersection of vision-based theories of L2 motivation (Dörnyei, 2009), Self Determination Theory frameworks (Noels, 2009), and narrative, life-story approaches (Dörnyei & Ryan, 2015), I explain how it can inform the investigation of motivational persistence.
