Have finally found the original of the quote that I used in Princess Tutu: Enchantment. Oddly, I did not find it in the inspirational quotes calendar where I'm still pretty sure I originally found it (maybe it was in last year's?), but rather in a quilting magazine from 1993.

In any case, "Use what talents you possess. The woods would be very silent if no birds sang there except those who sang best." --Henry Van Dyke
