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 do something late than not to do something at all
A dime a dozen
Something very common
Cut somebody some slack
Don't be so hard on someone
Get your act together
Starting doing better or leave
Go back to the drawing board
Start over
Hang in there
Don't give up
Hit the sack
Go to sleep
Give someone the benefit of the doubt
Trust what someone says even though you are not 100% sure they're telling the truth.
Let someone off the hook
To not hold someone responsible for something
On the ball
Doing a good job
Miss the boat
It's too late
Make a long story short
Tell something briefly
