Don't read, just go out and do it. Its simple logic. You don't like paying a heating bill in the winter, go and cut some wood and build a fire or just wear a heavy coat. Don't like paying a water bill, build an outhouse or bring in a honeypot. Ect, ect. My mother has just about every self help book that has been on Opera (and she does read them) and they havn't done a thing because she is using them as a method instead of a reference. Books on simplicity can be a good reference, but the method or philosophy if want to call it that must be your own.
Just out of curiosity, are you willing to use a honeypot or outhouse in your daily life?
Also here is a pretty cool blog.
