I’ve kept a sleep journal for years. I was inspired by the book “The Promise of Sleep” and basketball star Steve Nash. Using Excel formulas, I now have it automated to spit out the average time I go to bed slash get up and my average amount of sleep. As crazy and regimented as it might sounds, it’s pretty effortless and make a huge difference. Don’t believe it? Check out the book or just implement a sleep journal. You’ll be happy you did.
