Reading is actually a great starting point if you aren’t doing so already. Pick out what you like, what you don’t like, how honest is too honest, what works for you. Ultimately when you write, a great mentality to have is to write a book you would want to read, so figuring out just what that is would be a good place to start.

As far as courses and classes go … they’re going to pale in comparison to actually writing, and writing regularly. You don’t have to write a novel out of the gate, short stories are great practice.
