I was literally laughed at when I was 17, back in the 80s, and I told the worker at the employment service I wanted to be a radio announcer.
“Yeah. Ha ha ha! Jobs like that don’t come through here.”
But three weeks later, there I was, sitting in the studio of a radio station ready for my first shift.
