I have just read/heard “Don’t Trust Your Gut: Using Data to Get What You Really Want in Life” by Seth Stephens-Davidowitz, at Mofibo. My friend are getting tired of me continually quoting from the book. You can read it here: https://mofibo.com/dk/books/don-t-trust-your-gut-using-data-to-get-what-you-really-want-in-life-924779

There is a good, short review at Wired Magazine here: https://www.wired.com/story/data-marriage-behavior-love-psychology-romance/

I've worked with databases for years, so I'm used to using data. But Seth takes it to a different level. An example: he also writes about how to get a successful business.
