I especially like the "Finish it" tip. I spent years on my very first novel and few things have made me feel better than actually finishing the damn thing. Of course, it's a first novel and as such has a bad case of being a first novel, but I finished it, and learned a lot in the process. It's all about going from "I'm writing a book" to "I wrote a book." Many people say the former, not nearly as many say the latter.
