This anecdote was posted on my first blog on June 14, 2012:
Lotte Lehmann became a famous opera singer just before WWI and performed a total of 93 roles in her career. She retired from the opera in 1951 and became a music teacher for over twenty years.
One day she was visiting with an up-and-coming young soprano who remarked sympathetically that “It must be terrible for a great singer like you to realize you’ve lost your voice.”
“Not at all,” the older lady replied. “It would be terrible indeed if I didn’t realize it.”
To everything there is a season… including a time to quit – before you become an affliction rather than a delight to your audience.
