The idea of occupational devotion, or devotee work, was conceptualized and incorporated in the serious leisure perspective as one of the two serious pursuits. The other pursuit is serious leisure itself, with both forms being anchored in activities that are immensely appealing and fulfilling. Despite such desirable qualities the serious pursuits constitute a minority of all work and leisure, these two domains being dominated by disagreeable work and hedonic casual leisure activities. The devotee occupations serve as full-time or part-time livelihoods for people fortunate enough to have found them. Such work has so far been observed to exist in four sectors of the economy: the liberal professions, consulting occupations, craft-like trades, and creativity-based small businesses. In ways set out in this book, devotee work roots in serious leisure, even while many participants in the latter have no desire to pursue the former.
