Followers of the Financial Independence, Retire Early movement (F.I.R.E. Movement), Kristy Shen and Bryce Leung, retired in 2015 and have been traveling the world ever since. Shen, 36, and Leung, 37, spent years saving and investing their money, so they could quit their jobs before the ‘traditional’ retirement age. Together they published ‘Quit Like a Millionaire,’ and run the blog, Millennial Revolution. After Leung looked in to investing money in low-cost index funds, he realized that financial independence was possible. In 2012, they made it official by saving and investing, and in three years, they quit their jobs to travel the world for a year. They loved it so much; they kept traveling, and have not stopped since. They realized living in other countries, like in the Eastern part of the World, would be significantly less expensive to live per year than in the U.S.
