reading Why we sleep, by Matthew Walker. After reading this book I decided to put sleep quality above everything and it helped me take the adequate measures. What worked for me was : lowering my caffeine intake (no more than 2 coffee), no caffeine in the afternoon, no screen in the evening, no work 2 or 3 hours prior to go to bed, increasing exercise and sunlight exposition in the day. Oh and good earplugs !

Agreed. You can read about hacks and techniques to improve sleep all you want, but many people will fail to consistently implement those. Why We Sleep gives you the "why", highlighting consequences of poor sleep and the "how" science of those techniques working.
