This weekend I'll be at the annual PNWA conference. If you're attending, please find me and say hello!
And remember to attend local conferences. Get involved.
Network with not only agents and editors, but also other writers. You may be able to find a new critique group more tailored to your needs. They may be able to impart advice, such as finding agents or other conferences/workshops to attend. They may be the voice at midnight you need to help get you through your first draft/multiple edits.
Take time to implement changes to your ms after attending workshops before sending it out to agents you've pitched at the conference.
Take advantage of extra pitch session time to ask advice.
Take advantage of having book doctors there to let you know where you are at with your novel and what you can do to step it up
But always, ALWAYS have fun!!
