Pete Adeney (Mr. Money Mustache)
Single-handedly popularized FIRE on the internet. Living proof that FIRE is achievable for the middle class with discipline. The math post is required reading for every frugalist.
Abstract
Influential blog that popularized FIRE in the mainstream. Seminal post "The Shockingly Simple Math Behind Early Retirement" shows that savings rate is the ONLY factor that matters for time until FI. MMM demonstrates with simple math: 50% savings rate = 17 years until retirement, 75% = 7 years. The blog mixes practical finance, Stoic philosophy, efficiency, and life optimization. Adeney retired at 30 with wife and son, living on $25-27k/year. Emphasizes smart frugality (not deprivation): biking vs driving, DIY, geo-arbitrage, anti-consumerism. Tone is irreverent, direct, sometimes controversial—calls "complainypants" those who make excuses. Created massive community of "Mustachians".
