Writing a thesis by publication presents a number of writing challenges that one is likely to start noticing from the very beginning because this thesis format can be seen as a ‘hybrid practice, performing both public and pedagogical functions. This chapter discusses the typical challenges related to writing a thesis by publication: writing the articles requires one to write like an authority, and the narrative requires one to take the role of a student to show the thinking and the ability to understand one's own work. It describes these processes in some more detail before turning to some ways of developing writing habits that might help in ­handling this complex ­process of juggling different writerly identities. Writing with a set schedule helps reinforce the importance of breaks. What sets writing a thesis by publication apart from writing a monograph is that it, by definition, requires one to juggle different manuscripts in different stages of completion.
