Your Money or Your Life: Transforming Your Relationship with Money and Achieving Financial Independence by Joe Dominguez and Vicki Robin
Probably the book with the greatest influence on my life. I read it in my 20s, and it made an impression then, but it didn’t stick. After re-reading it a few years ago, the effect has lasted. Dominguez and Robin suggest a new way of looking at money and paid employment, to realize that in a way, we are “selling” our lives to earn money to buy stuff. It gave me a new respect for the money I earn, for the work I’ve chosen in order to earn it, and for my own financial decisions.
