Konarski was born in Kiev and attended a Polish school there. In 1921, he was able to get to Poland by foot. He passed his matura (final exams) in Warsaw. He began to study Polish at Warsaw University, but found his calling on stage. A deciding point was encountering Konrad Tom, who helped Konarski begin authoring poems and songs, as well as suggesting the "Ref-Ren" stage pseudonym. In addition to songs, Konarski also wrote satirical plays for theater groups. In 1931, he married the actress Nina Oleńska.
