“Count your chickens before they hatch”
Assuming something you want to happen will definitely happen
“In a pickle”
Have a tough choice or problem, possibly in trouble
Cool as a cucumber
To be very calm, with no worries
“Hit the nail on the head”
To do or say something that is exactly right
“Bigger fish to fry”
Have more urgent problems
“The icing on the cake”
Makes something even better
