I'm always reading new things to improve my knowledge of writing and music. It's amazing that after studying music for over 30 years and getting a masters degree, there is still so much for me to learn. With writing, it's even a bigger prospect. I know a little, but every time I read a book about writing, go to a lecture/panel on writing, or listen to a podcast, there's always something new for me to learn. It's exciting and scary.
For instance, I'm doing yet another draft of The Dragon War Relic. Every time I read it, I find more things that need to be fixed. Part of that is because each time I do a new draft, I have new knowledge that I can apply.
Why did I have to pick two arts that require a lifetime of study?
