For me writing is a long, hard, painful process, but it is addictive, a pleasure that I seek out actively. My advice to young writers is this: Read a lot. Read to find out what past writers have done. Then write about what you know. Write about your school, your class, about your teachers, your family. That's what I did. Each writer must find his or her own kind of voice. Finally, you have to keep on writing.
I tried to go to community college for a while, and it's a funny story. I walked into the English class on the first day, and they told us to write about what we did over the summer. I can't remember exactly, but I think I walked out exactly at that point and went to the office to ask for my money back.
I may have a general broad-based idea of what I want to write about when I sit down to write a book, but I don't have any idea of what it's going to say. I would call my experience of creativity 'inspired by God' to produce certain pieces of information that might be useful to others.
