Writers have great imagination! I always admire people who could write “Harry Potter,” “Game of Thrones” or “Star-Gate” with their elaborate worlds & family trees. These worlds are ALIVE in the imagination of their authors. Sometimes I heard that these characters (protagonists) are impatient to come alive, on stage, in a book or movie. No writers block for sure. Almost as if they travelled to the future in a #timemachine and came back to tell us!
Doing that for a living and charging Nike, GE, Citi or Intel to play & live in a dream world, must be fun! Some people just have all the luck!
