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
A blessing in disguise
a good thing that seemed bad at first
Go back to the drawing board
Start again from the beginning
Hang in there
Don't give up
Hit the sack
Go to bed
Give someone the benefit of the doubt
Trust what someone says
On the ball
Doing a good job
Miss the boat
To miss an opportunity; to lose out on something
It's not rocket science
It's not complicated
Pull someone's leg
To joke with someone
Wrap your head around something
To understand a complicated idea, situation or process
A picture is worth 1000 words
Better to show than tell
Actions speak louder than words
Believe what people do and not what they say
