Here is an early, terribly down to earth, video interview of beloved author J.K. Rowling. In it you can sense her eagerness to write and her commiserating statement that she dreamed (as most who write do) of supporting herself through writing.
As of this video she was writing Harry Potter and the Prisoner of Azkaban. You may be intrigued to hear that she says there will be more books of some sort after Harry is done and that she fancies being “Big in Finland”, in a very modest way. May you be inspired by her humility and be filled with a desire to place words on the page.
