Early Retirement Extreme by Jacob Lund Fisker

A philosophical and practical guide to financial independence

A rigorous, systems-oriented manifesto advocating extreme frugality and skill-building to achieve financial independence far earlier than conventional retirement plans. It emphasizes simplifying life and reducing consumption to dramatically lower living costs, increasing savings through efficient behaviors and replacing paid services with DIY skills, then investing the surplus to secure long-term freedom. The approach treats lifestyle design as an engineering problem—prioritizing resilience, autonomy, time affluence, and rejection of consumerist norms rather than mere budgeting tricks.
