Query: Who said that Chopin set out "into the wide world, with no very clearly defined aim, forever?"
Context: Chopin's successes as a composer and performer opened the door to western Europe for him, and on 2 November 1830, he set out, in the words of Zdzisław Jachimecki, "into the wide world, with no very clearly defined aim, forever." With Woyciechowski, he headed for Austria, intending to go on to Italy.
