You can't write a book if you've never read a book. And if you've read five books and you try to write a book, your book will mainly encompass the themes and the context of the five books you've read. Now, the more books you read, the more you can bring to a book when you decide to write one. So the more rap I learned, the more I was able to bring to rap when I decided to rap. But this was all subconscious.
