If your German is good enough, you might enjoy this interview with Jonas Kaufmann. He speaks at length about his vocal crisis. I am sticking to translating interviews that are written out.
He talks about his vocal crisis and what he did to overcome it. He talks about how babies never seem to get hoarse. This is amusing. Undoubtedly the words of a father. Singers strive to achieve the same naturalness that a baby has naturally. The point never comes when one can say that one has achieved this. It's necessary to keep striving.
