“Head over heels”

“All ears”

Ready to listen carefully.

“By the skin of your teeth”

Barely; just in time.

“Dig your heels in”

To refuse to change your opinion or position.

“Fish out of water”

Feeling uncomfortable in an unfamiliar situation.

“Cross that bridge when you come to it”

Deal with a problem when it happens, not before.

“Keep your fingers crossed”

Hope for good luck or a good outcome.

“Easy does it”

Go slowly and carefully.

“Hit the road”

To leave; start a journey.
