There are a lot of people out there who are doing really cool stuff. Here are a few places to check out:
Jacob at Early Retirement Extreme is the real deal. Through extreme saving and extreme frugality Jacob retired at 33 and is living an active and fulfilling life.
Tim Ferriss at 4-Hour Workweek is a master self-promoter. When you filter out some of the nonsense in his books you are left with a compelling and unconventional approach to life. The main takeaway that I got from The 4-Hour Workweek is mini-retirement but there is something in there for everybody. Read the book.
Glenn at To Simplify is a professional musician who lives in a small motorhome. His writing is fun and engaging and his approach to simplicity is philosophically deep-rooted. He gets extra points for being a serious crossword puzzler.
