You've read the sleep tips. You know about blue light and caffeine. But as an entrepreneur, your sleep problems run deeper. Racing thoughts at 3am. The weight of payroll. Fundraising anxiety that follows you to bed. Positive stress from a big win that keeps you wired until midnight. Sleep Again is the first sleep book written specifically for entrepreneurs and founders. Joakim Achrén spent over 20 years building companies, including a game studio acquired by Netflix, and sleeping terribly the whole time. After a burnout in 2019, he spent two years researching why entrepreneurs specifically sleep worse than everyone else, and what actually works to fix it. This book covers sleep science, lifestyle factors like caffeine timing and overtraining, mental strategies for racing thoughts, and a practical toolkit you can start using immediately. 27 chapters. 87 endnotes from peer-reviewed research. No fluff.
