I grew up on a healthy diet of fantasy. As is fairly normal in childhood. From Disney movies to books with children going on adventures, to the stories that played in my mind. In my family, reading, and artistic endeavors, and imagination were encouraged. I took drawing lessons where I learned how to see objects for what they were and make them come alive in a different world, one of graphite and charcoal.
Questions! Questions! Questions! Are you trying to come up with a plausible story to write about? Sci-Fi? Romantic? Adventure? The selection of topics can be overwhelming. What appeals to you? What do you feel comfortable with? Is there an experience you’ve had that can guide you? How much effort is needed to put into it? Do you have the requisite time?
