Josue Lajeunesse, a lead janitor in Princeton's building services department, is one of eight college custodians whose stories are the subject of the new documentary film, The Philosopher Kings. In the trailer for the film, Lajeunesse is seen stressing the value of a well-rounded life. "If you don't have happiness, you don't have a life," he says, sharing a laugh with his son. "To be successful, you need the balance inside and outside." The clip is 3:38 in length; Lajeunesse can be seen at :57 and 2:10 into the clip.
