Since my daughter was born, I've taken getting my finances in order way, way more seriously than I ever did before. In fact, I had a freak out when she was a few weeks old, started looking closely at my financial records, and decided I needed to do something about it all, particularly if I ever intended to send her to college or some other useful thing.
The first step, for me, was Personal Finance blogs. I started with Get Rich Slowly, just going back and back into their archives until I had read almost everything they had. GRS was founded by JD Roth but is now run by a company and has multiple authors, all in various stages of financial health. From there, I found a bunch of other good blogs, my favorite of which is Mr. Money Mustache. I like MMM because he's a little more irreverent and funny (and having spent much of my career around contractors, cursing doesn't bother me).
After devouring the archives of several PF blogs, a few book titles came up multiple times as being very influential for the bloggers own lives. Foremost among these was Your Money or Your Life. YMYL is about, above all, having enough and living your life to your best purpose, by letting money support you and not drag you down. It's simultaneously practical (how to save, etc.) and very powerful.
The other book I read and really liked was the well-known book The Millionaire Next Door. This takes a very statistical dry look at financial health by using surveys to identify real millionaire's common traits. And by real millionaire, I don't mean the flashy guy driving a Bentley but who has two mortgages and no savings, but the man with the paid-off house in the good, but not prestigious neighborhood, who never has to work for a living again. Underneath the statistics, Millionaire Next Door is, like YMYL, about having enough.
Let me know if there are any good PF blogs or books you'd recommend.
