When work is a pleasure, life is a joy! When work is a duty, life is slavery.
Gorky isn't merely celebrating passion projects—he's describing a philosophical divide about *agency*. The distinction cuts deeper than happy versus unhappy: pleasure implies you've chosen the work and own its meaning, while duty suggests external compulsion has colonized your time and identity. A surgeon might perform the same operation with either disposition, but only in the first case does she experience herself as free. The sobering part is that we often don't notice when duty has quietly replaced pleasure, which is why someone can wake up fifteen years into a "successful" career and realize they've been serving an obligation they never actually accepted.
