hold your horses
wait a moment
cost an arm and a leg
very expensive
call it a day
stop working on something
break a leg
good luck
Better late than never
Better to arrive late than not to come at all
Hang in there
Don't give up
Hit the sack
Go to sleep
On the ball
Doing a good job
Under the weather
sick
Give someone the cold shoulder
Ignore someone
Once in a blue moon
Rarely
Saving for a rainy day
Saving money for later
The ball is in your court
It's your decision
