October 30, 2014: Imagine getting hit by a tree branch and waking up in the ICU, finding out your husband is having an affair, and losing a job you love—all in less than a year! Heidi Siefkas doesn’t have to imagine it because it happened to her. She’s written about her terrible, horrible, no good, very bad year in her new book When All Balls Drop: The Upside of Losing Everything. Heidi will be appearing at the Brookline Booksmith, 279 Harvard Street, on Sat. Nov. 1 at 4PM. I spoke with Heidi by phone about the nature of resilience and why she decided to share her difficult story.
