Pull yourself together
Calm down
Under the weather
Sick
Wrap your head around something
Understand something complicated
We'll cross that bridge when we come to it
Let's not talk about that problem right now
A bird in the hand is worth two in the bush
What you have is worth more than what you might have later
A penny for your thoughts
Tell me what you're thinking
A perfect storm
the worst possible situation
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
By the skin of your teeth
Just barely
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
Look before you leap
Take only calculated risks
On thin ice
On probation. If you make another mistake, there will be trouble.
