Ask HN: What book changed your life in 2013?
The most significant book for me was in the area of health and fitness as I finally read The 4-Hour Body (2010) by Tim Ferris. I'd read about many of the topics he covers before but they just didn't stick until The 4-Hour Body. What I like about Tim's approach is that one should experiment to see what works rather than following a rigid plan. I tried many of his suggestions and some worked for me while others didn't. The binge day was particularly bad so now I just follow the same plan every day; as well I had to increase the amount of carbs before my last meal of the day to get a better sleep. But experimentation and tracking my results has made all the difference from other diet and exercise changes I've attempted in the past. It's definitely worth the read even if experimentation and tracking are the only things you get from the book.
Thanks for a great community and I look forward to your suggestions.
