Get it together, dievča!

Natalie Wood, pie fight from The Great Race

The idiom: брать/взять себя в руки
Literal translation: “To take oneself in one’s hands.”
What it means: “It means ‘to pull yourself together.’”
Other languages this idiom exists in: Translators tell us that there is a German version of this idiom too: “Sich zusammenreißen,” which translates literally as “to tear oneself together.” And in Polish, the same idea is expressed by the phrase, “we take ourselves into our fist (wziąć się w garść).”
