Your Money or Your Life by Joe Dominguez & Vicki Robin
A very TreeHugger-esque philosophy is expounded here. Your Money or Your Life helps you understand your relationship to money. How you get it, where it goes, and how inconsistently you value it. The goal it sets up is to move toward a state of financial independence, so that you can spend your time doing what you’ve always wanted to do (which, the authors intimate, should be save-the-world-type stuff). Importantly, the authors exhort you to really understand your expenses and to reduce them to those that bring you the most pleasure, and nix the rest. Compellingly, this doesn’t mean giving up your expensive Japanese porn collection or SoHo House membership, if you determine that they’re essential to your happiness and well-being. Secondly, they teach you to calculate your actual hourly wage, including commute, clothing, work-related downtime (a lot lower than you might expect), and consider your purchases using this metric. That shirt that you don’t really need may look different when you realize that it causes you to be another 1.2 hours away from doing what you really want to be doing.
