I spent several years acquiring the obsessive, day-to-day discipline that's needed if you want to write professionally, then several more, highly valuable years studying fiction writing at the University of Iowa.
In Berlin I especially enjoyed the orchestral concerts, and I attended a large number of them. I formed the acquaintance of a good many musicians, several of whom spoke of my playing in high terms.
So we used to look for funny songs, and learn them and play them. And we used to play them in pubs.
