Here are the first verses of Goethe's Gefunden:
Ich ging im Walde
So für mich hin,
Und nichts zu suchen,
Das war mein Sinn.
My question is about the meaning of so für mich hin.
From what I could find, this doesn't seem to be an usual collocation (correct me if I'm wrong).
My first guess, based purely on intuition, was that it means something like "for my sheer pleasure" or "just by desire".
By the translations I've found on google, it means either "by myself" or "on a whim of mine", both of which apparently make sense on the context.
