Author Matthew Walker Genres Self Help Rating 💖💖💖🖤🖤 Date Finished ~2023 🎨 Impressions I’ll keep the review short and concise. My first impression of the book was good. I thought that anyone striving to improve their sleep quality should have read it. But after reading the article Matthew Walker’s “Why We Sleep” Is Riddled with Scientific and Factual Errors I’m not sure anymore.

Author James Clear Genres Self Help Rating 💖💖💖💖💖 Date Finished ~2022 🚀 The Book in 3 Sentences Habits compound over time and decay if not maintained. Focus on creating a system not a goal.

Author Johann Hari Genres Self Help Rating 💖💖💖💖🖤 Date Finished 17/12/2023 🚀 The Book in 3 Sentences Systemic problems require systemic solutions; individual solutions are only a temporary measure. The best engineers in the world are working to steal your attention and derail your focus. We are in what could be called surveillance capitalism, where we are digitally monitored so that advertisers can understand us and target us with as many ads as possible. 🎨 Impressions I like the book. It doesn’t offer a solution and it doesn’t pretend to offer one because there is no solution. The author even admits that he only partially fixed the problem of spending too much time looking at a screen. I like how it addresses various problems, smartphone related ones, like food quality, dangerous untested substances, and ADHD. ...
