At an addiction shelter called La Casita, in Puerto Rico, male residents espouse an ethic of busyness. Initially, La Casita's ideology of moralized work patterns and time discipline seems like a throwback to the 19th‐century factory floor: a tool of market discipline. But a closer look at residents’ experiences reveals that busyness has less to do with capitalist subject formation than with finding an alternative way of living when one is excluded from the labor market. If the capitalist project turns on the productive commodification of time, La Casita's work ethic—despite official avowals to the contrary—aims to convert unproductive time into an ascetic practice of ceaseless self‐work. Though not always successful, keeping busy becomes a way for residents to carve out a meaningful way of living from an overabundance of time.
