One of the most important writing investments would be your bio or profile for your business page and yourself. Think about your LinkedIn pages or website “About” page. Investing your time and effort (or contracting a writer) is worth it – once you create an impressive profile it will last a long time and serve you well!
A media kit (or press kit) is a great way tool to have for a launch date or event. It ensures everyone has the correct information (including correct spellings) and can even include pre-packaged tweets or Facebook updates to help others help you get the word out.
