Your Money or Your Life by Vicki Robin

Your Money or Your Life remains the definitive FIRE movement classic, demanding readers calculate every purchase's cost in life energy hours worked. Vicki Robin's method reshaped a generation's spending mindset, with adherents typically saving 50% more of their income than the average American household. Unlike typical personal finance books that focus on simple budgeting, this text challenges core assumptions about work and consumption, offering a concrete 9-step program to achieve financial independence. Its time-based valuation system helps users cut discretionary spending by 30% in the first year, outperforming #6's debt-focused approach in long-term wealth accumulation.
