Most of my career I have worked on projects or managed teams or clients distributed across Australia and increasingly the world. So when we have needed to work together face to face ive happily travelled. The benefit of being childless and currently dog-less is that I can usually be available to fly at short notice when often other colleagues cant.
If travelling for work I will often stay on in a city for a day or two extra over the weekend at my own expense to check out things clients or colleagues recommend; as long as the return airfare cost isnt impacted.
As to why I travel on my own dime well its is because there so many places I've read about or seen on tv that I want to experience for myself and being an extrovert love striking up conversations with locals and fellow travelers alike. I love to eat authentic food, explore area outside the tourist traps to see how the locals experience a place although many touristy things are also still worth doing.
I want to visit so many places, every time I tick one off i usually end up hearing about others I add to my list. I want to go whilst im fit and mobile enough to do all the activities, be that swim/dive/snorkel, kayak or hike. I dont want to find myself retired with insufficient funds, or mobility issues or illness and then have regrets.
I try to go to at least one new overseas destination (be it a country, city or region) a year and also try to go somewhere in Australia I haven't been. But I also love to return to favorite places and challenge myself to find new experience there and visit the many friends i have all over the world.
Whilst I love my home city and my home, if I've got more than a normal 2 day weekend off you wont find me here, I'll be somewhere else.
I'll never understand people who don't use their annual leave, I always use mine and usually take extra leave without pay because the opportunity cost of not doing so is way too high imo.
