Easy
No pain, no gain
You have to work for what you want
Pull yourself together
Calm down
Under the weather
Sick
A picture is worth 1000 words
Better to show than tell
It's a piece of cake
It's easy
So far so good
Things are going well so far
Better late than never
Better to arrive late than not to come at all
Your guess is as good as mine
I have no idea
Actions speak louder than words
Believe what people do and not what they say
Get a taste of your own medicine
Get treated the way you've been treating others (negative)
Make a long story short
Tell something briefly
Call it a day
Stop working on something
Give someone the benefit of the doubt
Trust what someone says
Break the ice
Make people feel more comfortable
Don't cry over spilt milk
There's no reason to complain about something that can't be fixed
It's not rocket science
It's not complicated
Hang in there
Don't give up
We'll cross that bridge when we come to it
Let's not talk about that problem right now
Comparing apples to oranges
Comparing two things that cannot be compared
Don't count your chickens before they hatch
Don't count on something good happening until it's happened.
Speak of the devil
The person we were just talking about showed up!
Break a leg
Good luck
You can say that again
That's true, I agree
Barking up the wrong tree
To be mistaken, to be looking for solutions in the wrong place
Costs an arm and a leg
Very expensive
