Lesson 1. Do not attempt a complicated novel when you don't understand what you're doing yet.
Lesson 2. If you don't know where you're going or how even to accomplish it in a non-linear story, do not expect the story to just write itself.
Lesson 3. Do not attempt stories that require a lot of research without actually doing the research prior to nano.
Lesson 4. You can still write 50,000 words while not knowing what you're doing.
Lesson 5. Those words will be crap.
