Abstract
Cost, constraints, and perseverance—three closely related terms in the serious leisure perspective (SLP)—have been identified by Lamont, Kennelly, and Moyle (2015) as in need of some clarification. This note attempts to clarify the relationship of the three, based on how they have been defined and interrelated over the years in the SLP. The concepts of constraint and cost play a number of different roles in the SLP. It therefore seems best to retain them as separate ideas, despite the doubts raised by Lamont and colleagues. Perseverance also plays a couple of roles in the SLP, which likewise justifies keeping the idea separate from cost and constraint, again contrary to the doubts posed by Lamont and colleagues.
