hold your horses
wait a moment
cost an arm and a leg
very expensive
break a leg
good luck
Get your act together
Work better or leave
Hang in there
Don't give up
Hit the sack
Go to sleep
It's not rocket science
It's not complicated
No pain, no gain
You have to work for what you want
Pull someone's leg
To joke with someone
Pull yourself together
Calm down
Under the weather
Sick
Give someone the cold shoulder
Ignore someone
It's a piece of cake
It's easy
It's raining cats and dogs
It's raining hard
Let the cat out of the bag
Give away a secret
On thin ice
On probation. If you make another mistake, there will be trouble.
