Tip: When attending conferences or submitting, come prepared. Bring a well polished query letter, synopsis, and up to the first fifty pages of your manuscript (though ten is usually enough). Bonus tip, when going to agent or editor meetings, bring a notepad and take notes based off what they say. Just be sure to stay engaged and make eye-contact periodically.
How about you, any writing tips to share that are related to submitting or conference going?
