It's crazy, but these are totally common sense rules. It really just means that you need persistence in order to be a writer. Though I will say, it's definitely hand to read those "the process of writing" books, before you publish your 1st manuscript. After is fine too, but the ratings beating can be a morale killer.
Great rules- and now with so many choosing to self-publish I'd add a rule- Have your work edited before presenting it! We use an editor, a proof reader and a beta-reader or five before we publish. Even a good story can turn off your readers if it is full of typos, misspelling and errors.

Some really good tips from these rules, and Robert J. Sawyer's comments on each are great too.
I especially like Rule #5: You Must Keep it on the Market until it has Sold
