Rule reminder
After modal verbs (volere, dovere, potere) and after prepositions (di, senza), use the infinitive 'andarsene': 'Voglio andarmene' = I want to leave, 'Deve andarsene' = He has to leave, 'Senza andarsene' = Without leaving.
It's not easy to leave everything behind. → Non è facile ___ lasciando tutto.
