Proverbs from your country

I thought it would be fun to see what kind of proverbs people have in other countries and will start with a few German ones.
"Wer andern eine Grube gräbt fällt selbst hinein". ("He who digs a pit trap for his neighbour will fall into it himself").
"In der Nacht sind alle Katzen grau". ("At night all cats are grey").
"Morgenstund hat Gold im Mund". ("Morning hour has gold in its mouth").
"Wer den Pfennig nicht ehrt, ist des Talers nicht wert". ("He who does not honour the penny is not worth the shilling"; I had to use diferent coinage for translation).
"Lügen haben kurze Beine". ("Lies have short legs").
"Wie man in den Wald hineinruft, so schallt es heraus". ("As you call into the forest, thus it will reverberate").

What are some of your proverbs?

"Fool me once shame on you, fool me twice we won't get fooled again"(or something to that effect)  - George W. Bush

If you can keep your head when all around are losing theirs, you either don't realise how bad the problem is, or you're a bad helicopter pilot.

We have proverbs for those same ideas as well:

Cine sapă groapa altuia cade în ea. (#1)
Minciuna are picioare scurte. (#2)

Ah, "someone else" beat me to it. 

A shut mouth catches no flies.

An Italian version of the above proverb: "L'ospite è come il pesce - dopo tre giorni puzza" (guests are like fish - on the third day they start stinking).

You attract more flies with honey than vinegar.

Although I am completely in favor of changing "flies" to something people would actually want.

Mexican version of the same "Las visitas y los muertos a los tres dias apestan" (guest and dead people on the third day they start stinking)
