Dr. Barbara O'Neill is launching a new book titled "Flipping a Switch" about financial, social, and lifestyle transitions in later life. She is promoting the book through a 35-day Twitter campaign called #35DaysofFlippedSwitches that will involve daily graphics and tweets discussing transitions and including a question. The campaign is modeled after a previous successful savings challenge. Initial data shows the book reaching Amazon best seller lists and the campaign gaining a large Twitter reach and impressions through retweets by influential financial accounts. Recommendations are given for replicating a similar promotional campaign.
