A friend passed along a link for an interview with Jane Yolen, who needs no introduction! In answer to what it takes to write 300 books, Jane said, "BIC. Butt in chair. Every day."
How simple yet profound. How simple yet elusive. Jane has obviously mastered it well. I am still working toward it.
I encourage you to go read her interview. It is quite inspiring. Thank you, Jane, for sharing!
