If you had the money to retire at 30, your savings would be invested and on an average year your earnings would cover your expenses. You would have health insurance, so no worries there. The only catch is that you would have to keep your expenses at 65% of what you spend right now. Would you take it, or would you rather work a few more years for a better lifestyle and financial security?
They did specify 65% of what you currently spend, not what you currently earn. I save a high percentage of my income too, mostly because I’m largely anti-consumption. Cutting my current spending down by 35% would be a bit leaner than I’d like to live.
