Now that I think about it, doing the amazing and interesting things are so anomalous, that one could probably make a bit of money doing them. Maybe that's why vloggers are so successful. Talk about having your cake and eating it too.
Making money is basically what every single long-term traveler is focused on, and I've yet to meet a single one who is actually paying for full time travel while traveling full time. A few of us (me included) get close by selling magazine articles, writing books, selling photos, etc. etc. It's a job, just a really, really fun job.
He mentioned he had a tech job at one point on one of his blog posts.
I studied Software Engineering in Australia, I work as that from time to time to top up the savings account, though I hope I never have to do it again.
Good luck and keep it up.
