Ten years ago, I had a cushy job at a big company and started to have thoughts along the lines of: Is this it? The timing couldn’t have been more perfect. At the behest of a close friend, I picked up The 4-Hour Workweek, and my perception about what’s possible in terms of work and travel completely changed. I used up all my vacation days and took a 4-week backpacking trip through southeast Asia, quit my job upon returning to the states, and set off to find my “muse” (in the book, a “muse” is an income-generating business that requires little maintenance).
