Why do prospective artists need a plan B when lawyers don’t?

Musiciain Blake Morgan, writing about his time at a school’s careers day:

The students’ faces lit up with curiosity. I added, “I hope you don’t listen to those other voices. I hope instead you listen to your own. That voice from inside you that guided you here today. I hope you go for it, with abandon and furious joy, and that you do so without a Plan B.”

Immediately, the teacher stood up and said, “No, no no…that’s wrong. You should always have a Plan B. Don’t listen to him, that’s not right.” She walked towards me to cut me off from speaking, and I said, “You see? Even here, in the arts and music room on career day, you’re being discouraged from answering your calling. From fully and freely going for this as a career choice.” I looked at the teacher and asked her, “Do you think the kids in the ‘doctor room’ are being told to have a Plan B? Or the kids in the ‘lawyer room?’ Or the ‘marketing room?’ No, they aren’t. And by doing so here, you’re telling these kids that this is a profession less deserving of pursuit. Less deserving of hope. Or necessity. Or respect.”
