If we bring a little joy into your humdrum lives, it makes us feel as if our hard work ain't been in vain for nothing.

Our reading
An editorial interpretation.
The speaker says that if their work brings a little cheer into dull, ordinary lives, it feels worth the effort. The tangled double negative, 'ain't been in vain for nothing', still lands as satisfaction, though the phrase 'humdrum lives' carries a faintly patronising note.
