After getting married in September 2009, my wife and I took a year to travel the world. It was an amazing time and though it cost us a year off work and a lot of money, I do not regret it for a minute. What I would regret however would be if we had not done it.
Too often I hear people say that they would have loved to do what we did, but they don’t have the time, money or have too many commitments to do it. Sure there are a lot of people who have commitments like kids, and sure it does cost a lot of money. The bottom line is that the exprience that you will have is worth so much more that the money you will spend. Plenty of people do it with children every year, and don’t get me started on why it doesn’t matter for your career.
