March 21 - Call your local business paper and tell them about your book and your platform and why you should be considered an expert in the topic area of your book. Pitch a story idea to them. Make it short and sweet, relevant and helpful. Once you get an article about your book (or you) printed in a publication, you have something on which to start building your platform and publicity portfolio. Save a copy of everything. Ask the publication if you can link to the article. If you reprint the piece, make sure you get permission and pay the fee to the paper. Don't "Do first and ask forgiveness later."
Key - Start small, but start somewhere!
