[backcolor=#FF0000]A rolling stone gathers no moss

moss是 青苔的意思，从字面上看来,滚来滚去的石子上面不会长青苔
比喻人不定心,反复改职业,故事业难有所成就; 另一方面可指对待感情有点游戏人生、吊儿郎当、居无定所、成不了家.
eg.Mr. Xian has had five jobs within three years.This will not get him very far.A rolling stone gathers no moss.
冼先生竟在三年内换了五次工作，这样浮游不定，又怎能有成就呢！

感觉很多英语谚语很有意思，我会慢慢发一些上来，也算是给自己复习or学习～～

I will remember it very clearly!
