You also a lucky to have job that gives you that flexibility. I do payroll/accounts and my better half is in IT not professions that have that kind of flexibility.
I was a stockbroker, wife in the govt and kids aged 8 and and 10.
I was fat, angry and stressed; Bec was pretty much a single mum, so we threw it in for a year and traveled.
We rented the house, which pretty much covered it's costs and away we went.
Fast forward 3 years and I now maintain gardens and lawns, my office the great outdoors, and biggest stress is if it's going to rain. Yeah and I've lost 30 kg.
We have a very different lifestyle to the one we left and am far happier and healthier than ever before. Sure we don't have the bucks we used to, but you can't buy time.
A few weeks ago an ex colleague of mine dropped dead on a cycling charity ride. Physically pretty healthy but this bloke had a LOT of stress in his work life. I'm sure his family would give all the things he's accumulated from this job that's killed him to be able to spend a few more years with him.
So yes you can chuck your job in and travel, it worked for me. And once the kids are a couple of years out of school we plan to head off again.
