Highly Recommend - Deep Work
And since we're on the subject of how we spend our time, check out Deep Work, Rules For Focused Success In A Distracted World, by Cal Newport. I recommend it to clients all the time. It's a great read and full of practical advice on ways to carve out time for your most important work. Whether you're in the corporate world and the lines between work and home are completely blurred, or a small business owner working far too many hours, I urge you to read this book!
