I'm completely over self-help books now. Why pay $20 to be taught that water is wet in 200+ pages. Exercise is good, drinking water is good, sleep is good, et cetera. The exact percentage doesn't really matter.
1. The frequency of a habit matters more for the development of a habit than the intensity. My chess coaching motto came from this book: "Consistency over Intensity"[1]
2. Most people are deficient in magnesium. Magnesium is considered the anti-stress mineral. A central symptom of the deficiency is insomnia. Personally, I started taking 250mg of magnesium supplement daily. [2]
3. Similarly, to the fight-or-flight response, there is pause-and-plan response. Your willpower can be increase by slowing down your breathing thus triggering the pause and plan response. This is something I do when I get intense cravings during my fast.[3]
4. Putting some tape over your mouth before bed can stop sleep apnea. Admittedly, I have stopped this(I will restart), but when I did, I had some of the most refreshing sleep.[4]
5. Another of my mottos, progress equals happiness came from reading self-help books. [5]
