Its a good first choice. It covers the basics all teachers should know about investing and finances. It talks to teachers directly. Talks about the pitfalls of annuities and benefits of index funds. Other topics too. Its been updated . I have read only the first, older edition so can't comment on the newer edition. For the cost of the book you have nothing to lose and everything to gain by reading it. You might also order his financial literacy-simplified. I also purchased that. Both were very helpful to me. I would buy both. They are quick reads.You can buy them on line directly from this site. Steve Schullo's book Late Bloomer Millionaires is also a good choice. What makes these books good choices is that they are written by teachers . Steve's book expands past just speaking to just teachers. Steve was an educator as was /is Dan Otter.
After reading those there are a multitude of many other books on Amazon like The Wealthy Barber or The Millionaire Next Door , which can continue to build your financial confidence. Just don't do Dave Ramsey or Suzie Orman as they sometimes give questionable advice and try to get you hooked into expensive products you don't need.
