This book changed my life, way back when I had a a preschooler and two elementary-aged children. We home-schooled, took care of thoroughbred race horses for our landlord, had a menagerie of farm animals and gardens, were heavily involved in teaching church classes and volunteer activities, and had multiple different extracurricular activities for the children, plus actually homeschooling and running a home! Life was crazy, I was struggling to juggle it all, and juggle it well. This book changed all of that.
After reading this book, I changed my scheduling habits drastically. I gave myself permission to say no to things. I taught this concept to all of my children, especially when they were learning to launch in their own lives. I use the precepts in this book as a business owner, when I'm training new employees, and juggling responsibilities in the workplace.
There are so many productivity and time management books on the market right now, but this happens to be the one that changed my life for the better. I'm an enneagram type 1, which means I'm always on the lookout for a new system by which I can live my life more productively. The ideas in this book worked so well for me, without causing more undue stress or adding to my to do list. On the contrary, it created a more peaceful home, a more peaceful life, and calmed the harried lifestyle I was living.
