Who doesn't run flies - quien no corre vuela (Spanish idiom)
As you can tell from the title, today we have another Spanish idiom: "(aquĆ) quien no corre vuela". It's a phrase that you use when you see that others are trying to gain some quick advantage. It could be used all the way from a domestic situation where, for example, someone at the table is trying to get all the "good" pieces, to financial markets on Wall Street where someone is trying to corner the market.
Since I don't suppose you'll want to say "who doesn't run flies" in English, I'll give you the English equivalent and you can apply it from there: "You've got to be quick (off the mark)" is the only equivalent translation I've been able to come up with. If anyone has a better one, be sure to send it to me using the contact link above.
