He who says little

I was thinking about this though, words are important, and this quote came to me, at least I paraphrase it.

He who speaks to much knows little, and he who speaks little knows a lot.

I think that is truthful, but this little thing popped into my head.

"Ah, but he who speaks to little will never be heard"

and

"Even if he knows a lot, if he does not say so, no one would know".
