1.) Actually get a working prototype done by Febtober. Have a quickstart ready by the time the bulk of the book is ready.
2) More and more playtesting. Lots of it. If my new-found disposable income does not preclude free time then have a playtest at a convention.
3) Post more or at the very least get into a regular posting frequency so it gets harder to blow off blogging.
4) Game more often and with more people.
