“Your Money or Your Life: Transforming Your Relationship with Money and Achieving Financial Independence” is a great book on freeing yourself up financially and getting your priorities clear.
I read it about 15 years ago and it changed my life. It helped me defined what was important to me and think up ways to get the life I wanted. Instead of focusing on getting more money, like most financial books, this one is about getting a more fulfilling life.
At the time there was a simple living series at the community college built loosely around the book. The teachers were all people trying for a simpler, more self defined life and they would offer good advice like: “Personal grooming—do as little as possible but not so little that people take notice.”
Note: This is a really popular book. You should be able to find it at most public libraries. If not, used copies are plentiful.
