I am wondering whether there is any routine, English proverb which is used to imply there is always someone better; so you have to prevent from being too proud of yourself.
I came across the metaphorical phraes a long time ago, however I had not enquire about it from native speakers and that's why I'm not quite confident whether it is an idiomatic and natural English saying which is understood and used by the majority of natives or not. It is:
- I saw a saw that saw a saw.
- I saw (past tense of the simple verb see) a saw (an instrument) that saw (verb) a saw (an instrument.)
First, please let me know whether it is a common English proverb. Second, please tell me if there is any better proverb/idiom/expression to imply that specially in AmE.
