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?
I’m not retiring until my house is paid off and I can include at least 1 large vacation a year into my budget. Those two things will probably happen simultaneously, but I’ve never heard of anyone paying off their mortgage by 30 in my life.
