Jason Fried and David Heinemeir Hansson
This book, written by two of Basecamp’s co-founders, offers a new path for working more effectively to build what they refer to as “the calm company.”
Their radical approach subverts the modern signals of success — the hustle, long hours, and a lack of sleep — in favor of a company culture and leadership that support calm, mindfulness, and self-care in order to reduce chaos and anxiety amongst themselves and their employees.
Review: “[F]or those in positions of power, this book shows it does not have to be a trade off between accomplishing something great and having a life outside work. I get that this is an uphill battle as popular culture celebrates the grinders, hustlers … the blood sweat and tears that people wear as a badge of honor. As the book title suggest, there’s a calmer way. This book shows it can be yes and, not either/or. Yes you can be effective at work, become rich, leave a dent in this universe and have a life outside it. Your legacy can be you left a trail of happy, healthy humans who genuinely thought of you as a good boss or manager. You’re happier. They’re happier. You can see your family, friends, and so can they. That seems pretty good to me, even if you don’t accomplish your mission of saving the whales.”
18. “Calm the Chaos Journal: A Daily Practice for a More Peaceful Life”
Nicole Ries Taggart
This one isn’t technically a book — it’s a journal. But this journal, specifically designed to help people with chaotic daily lives feel more calm, contains prompts and suggestions to encourage calm, foster self-care, and let the little things go.
This could be a good addition to your early morning or evening routine to get you into the right headspace at the beginning or end of a busy workday, and it gives you a chance to reflect instead of react in the moment.
Review: “I’ve been using this journal every night since I received it. It’s been helping me to prioritize how I spend my time and how to manage my feelings of wanting to “do it all” with something more balanced. I especially appreciate the section about planning the next day: waking up with an intention and plan to handle anticipated issues in a calm, thought-out manner has helped me to ease those frantic feelings of everything moving too fast. Plus, the beautiful design is wonderful to work with!”
