You decided to see the world, you worked hard (or at least long hours) at your job at Harvey Norman and saved up and travelled for a few months to a year doing odd jobs and gigs here and there. You've rinsed and repeated this process throughout your 20s.
While some travellers just become Resort walruses, not you, you're an experiencer. You go where others don't go. Perhaps you went to Nepal, perhaps Turkmenistan, perhaps you're hitchhiking on the back of a snow truck looking up at the Aurora Borealis
You reach your late 20s and been to every continent except Antarctica.
