zarywać noce

bite off more than you can chew

call it a day

cut corners

get the ball rolling

throw in the towel

back to square one

Let's not sweep this under the carpet; the unresolved problem will return at the next settlement.

I didn't want to act on my own initiative, so before contacting the client I checked who was handling the matter.

Let's not cling to the plan if the condition on which we based it no longer holds.

Let us not count our chickens before they hatch; the room is available, but the owner has not confirmed the booking yet.

That further change of date was the last straw; we asked for a fixed schedule.

Let us not put all our eggs in one basket; let us prepare a second meeting venue in case the room is unavailable.
