The first books I remember were classic children fables which I was simultaneously listening to on vinyl. In my room and listening to/reading them non-stop.
I always liked to write but I had to be "out of school" to start writing freely and enjoy it. I wrote an article that got published. Then I translated my grandfather's book from Italian. Then I wrote a screenplay. Then another one, and it won an award.
I guess the first who read my writing was my teacher in elementary school, but that wasn't fun.
