I
Break a leg
Good luck
Easy does it
Calm down
Better late than never
Better to arrive late than not come at all
Call it a day
Stop working on something
Get out of hand
Get out of control
Hang in there
Dont give up
Get your act together
Work better or leave/ Pull yourself together
Its now rocke science
Its not complicated
On the ball
Doing a good job
Miss the boat
Its too late
Hit the sack
Go to sleep
So far so good
Things are going well so far
Thats the last straw
My passion has run out
Pull someones legs
To joke with someone
Go back to the drawing board
Start over
