Mr. Money Mustache is the OG of the FIRE (Financial Independence, Retire Early) movement, and for good reason. Pete Adeney's no-nonsense, often humorous approach to frugality and wealth-building has inspired millions since 2011. The blog excels at challenging conventional spending habits with a blend of math, philosophy, and occasional face-punches of financial wisdom. His emphasis on reducing lifestyle inflation and finding happiness through simplicity rather than consumption remains refreshingly countercultural. While some advice skews toward higher earners and the archives can feel dated on specific investment vehicles, the core principles are timeless. Essential reading for anyone wanting to escape the consumerist treadmill and build genuine financial freedom.
