I recently had a student ask me if he was good enough for a specific ensemble he saw on television. I said no and he was sort of crushed. So I explained my response.
“It’s not that you couldn’t do it, but on your current path you’re not going to make it. However, you can always change
that path – that’s the great part! You can always hop on a new road. But that new road will require more practice, lessons, etc.”
That really helped to change the tone of, “No, you can’t do it.”
