This. Some friends of ours quite their jobs, sold their house and all their possessions to go travelling about 4 years ago. They were early 30s at the time and quite good jobs (Teacher and some legal job) to go to Thailand, Vietnam etc etc. Apparently they are planning to come "home" this year and start afresh.It doesn't. Do what makes you happy. Travelling was the best thing I did. Would love to do it again sometime.
Good for them, it's not for me. I'd hate to be mid 30s and just starting out again with house, job, family etc....
