It doesn't necessarily have a negative connotation, but using "merry-go-rounds" as a metaphor for life implies that life is always changing, which could be considered a bad thing. It depends on how you use it! Ex: Life is a merry-go-round, and I'm trying to hold on for the ride. Ex: Enjoy this merry-go-round called life.
