I like many English idioms such as "to pull up trees", "to give a second wind".
"To pull up trees" means to exert every effort to succeed, to do a lot of work to achieve great results. We have a Slavic analogue of it which sounds like "to remove mountains".
Example: After a good vacation I returned back to my work feeling like pulling up many trees.
"to get a second wind" means to get a new energy to continue something that is an effort.
Again our analogue: "to open a second breath". 
Example: I had been sitting zoning out and trying to focus on my current task until my colleague didn't bring me a cup of coffee. It gave me a second wind, I managed to concentrate and solve a problem in 2 hours.
Some of my favorites :
"water under the bridge" = " let bygones be bygones" - much has changed with time,let the past be forgotten.
"out of blue" - unexpectedly , suddenly.
" the whole nine yards " - completely, everything.
" the best of both worlds" - you benefit from different things that do not normally go together.
" wake up and smell the coffee" - be more aware, get with it , pay more attention.
" a finger in every pie" - an involvement in many activities.
" play it by ear" - wait and see how a situation develops, improvise.
