Pull yourself together
Calm down
Have your head in the clouds
To be impractical or to have ignore or be unaware of a problem
Time flies when you're having fun
Something feels quicker when it's fun
Break a leg
Good luck
Beat around the bush
Avoid saying what you mean, usually because it is uncomfortable
A dime a dozen
something very common
Under the weather
To be sick
A blessing in disguise
a good thing that seemed bad at first
Miss the boat
It's too late
Bite the bullet
To get something over with you don't want to do because it has to be done
To get bent out of shape
To be upset or angry
Let someone off the hook
To not hold someone responsible for something
That's the last straw
My patience has run out
Pull someone's leg
To joke with someone
Speak of the devil
The person we were just talking about showed up!
Hit the sack
Go to sleep
Wrap your head around something
Understand something complicated
Cut somebody some slack
Don't be so critical
Cutting corners
Doing something poorly in order to save time or money
On the ball
Doing a good job
Get something out of your system
Do the thing you've been wanting to do so you can move on
The best of both worlds
An ideal situation
Easy does it
Slow down
Call it a day
Stop working on something
