The meaning to the saying "a rolling stone gathers no moss" is as follows.
It is meant to suggest that while a stone moves continuously, it has no time to gather moss as moss will only be gathered on a stationery object.
This translates literally with the stone becoming a person and the moss becoming commitment, problems or anything perceived as negative, trying to gather on the person who in turn keeps moving, preventing problems gathering in the first place.
For instance a traveller could use the expression as a way to describe his life; wandering from place to place means he has no time to establish any ties, gain or form any relationships which could break down or encounter any of the day to day problems people generally tend to accumilate whilst going about their days; the expression "a rolling stone gathers no moss" could then be used by this person when asked to explain his life choice.
