Thinking of retiring early and living off your nest egg? The old 4% rule—where you withdraw 4% of your savings each year—might not cut it anymore.

If you want your money to last, consider dialing back withdrawals or mixing up your investments globally. Flexibility is the new money hack! #Business #Market #retirement
