5 Tips From Early Retirees

At 31, Robert Charlton had grown disillusioned with his job as a technical writer. "The idea of doing a desk job for another 30 years seemed painful to me, so I came up with this idea of trying to retire before 45," he says. He shared the idea with his wife Robin, who was then 31 and working as a travel agent.

Robert read up on personal finance instead of hiring an adviser and looked at taxable accounts they could draw from before turning 60. During that period, Robin completed an accelerated nursing program to become a registered nurse. By age 43, they'd gone from $16.88 in their checkbook at age 28 to saving up enough money to leave both their jobs and live off the interest.

"Really, we're very average people," he says, admitting that it's harder, though not impossible, for those with kids. "We never had power jobs. We just both took intelligent steps." Here are some of those steps.
