Used to travel a lot for work and when I left my job to go freelance as a consultant I resolved never to take a project that involved significant travel
5 countries on 4 continents in 3.5 weeks broke me
My passport says I've been to lots of countries I've never seen anything more than the airport, hotel and the client's office (and the taxi rides between)
Yes it was business class and 5 star hotels but there was sod all enjoyable or glamorous about it, when you're in your hotel room working every night till 2am
The only up side was that I got a shitload of air miles on the client's dollar. And a shoe box full of posh muni toiletries I'm still working my way through several years later
In my current role I have to go to Paris a couple of times a month but that's only Eurostar and so much more manageable
Give me my own bed and a reasonable length working day any day!
(She says, packing a bag for a work trip to Valencia. Have to be there on Monday morning which means travelling on Sunday. So that's half my weekend gone, sigh)
