Much has changed
One thing hasn't
I've been a copywriter for a long time, during which my enthusiasm has never diminished.
Clearly, in that time the way we go about this has changed massively.
What hasn't, and I hope never will, is incisive, sharp thinking is still needed to get work noticed, and acted upon.
I can point to many examples of doing exactly that, and I'd be very happy to do the same for you.
