I was one of the first hires at a growing startup called Bellhops. Somewhere along the way, I ended up working sixty hours a week. I was placing work above all else: faith, family, friends, you name it. Work was always my first priority. That was until June 4, 2015, when I collapsed at work and had three grand mal seizures. I was diagnosed with a grade 4 glioblastoma, which comes with an average life expectancy of fifteen months. Dear Jack is written for my son, but all parents can benefit from the life lessons this book teaches. Dear Jack encourages a Christian lifestyle while making parents think about a healthy work-life balance. Parents can use the lessons learned through my personal story to avoid future pitfalls of misplaced priorities.
