Interpreting proverbs is often complex, but is best done in a context. Interpreting proverbs from other cultures is much more difficult than interpreting proverbs in one's own culture. Even within English-speaking cultures, there is difference of opinion on how to interpret the proverb "A rolling stone gathers no moss." Some see it as condemning a person that keeps moving, seeing moss as a positive thing, such as profit; others see the proverb as praising people that keep moving and developing, seeing moss as a negative thing, such as negative habits.
