There are other fish in the sea
It's OK to miss this opportunity. Others will arise.
A dime a dozen
Something very common
Look before you leap
Take only calculated risks
call it a day
stop working on something
No pain, no gain
You have to work for what you want
Spill the beans
Give away a secret
The ball is in your court
It's your decision
Wrap your head around something
Understand something complicated
The best thing since sliced bread
A really good invention
There's no such thing as a free lunch
Nothing is entirely free
Get your act together
Work better or leave
Let the cat out of the bag
Give away a secret
Miss the boat
It's too late
break a leg
good luck
A penny for your thoughts
Tell me what you're thinking
Add insult to injury
To make a bad situation worse
Saving for a rainy day
Saving money for later
It's not rocket science
It's not complicated
We'll cross that bridge when we come to it
Let's not talk about that problem right now
Go back to the drawing board
Start over
Make a long story short
Tell something briefly
Give someone the cold shoulder
Ignore someone
Let someone off the hook
To not hold someone responsible for something
hold your horses
wait a moment
On the ball
Doing a good job
You can't judge a book by its cover
This person or thing may look bad, but it's good inside
Pull yourself together
Calm down
Throw caution to the wind
Take a risk
A perfect storm
the worst possible situation
Actions speak louder than words
Believe what people do and not what they say
Better late than never
Better to arrive late than not to come at all
cost an arm and a leg
very expensive
Hit the sack
Go to sleep
A picture is worth 1000 words
Better to show than tell
A bird in the hand is worth two in the bush
What you have is worth more than what you might have later
Pull someone's leg
To joke with someone
It's a piece of cake
It's easy
There's a method to his madness
He seems crazy but actually he's clever
Under the weather
Sick
On thin ice
On probation. If you make another mistake, there will be trouble.
Cut somebody some slack
Don't be so critical
Once in a blue moon
Rarely
Take a rain check
Postpone a plan
Take it with a grain of salt
Don’t take it too seriously
Hang in there
Don't give up
It's raining cats and dogs
It's raining hard
Put something on ice
Put a project on hold
Give someone the benefit of the doubt
Trust what someone says
A blessing in disguise
a good thing that seemed bad at first
Rain on someone's parade
To spoil something
By the skin of your teeth
Just barely
