I like the ethos and the philosophy of that worldview, HappyLife1977, but I would caution an 18 year old that 80%-90% of small businesses fail. You can indeed start a mobile business and thrive, but it's way more work than most people are willing to admit. Even something like mobile windshield repair is viable, but it takes getting your name out there, advertising, excellent people skills, being on time, and generating a lot of business by repairing people's windshields. It's doable, but it's hard. I see a lot of this sort of encouragement on this forum, but I don't see a lot of people showing that they are really making it work, to be honest.
I mean, who here is actually living a comfortable nomadic lifestyle funded by selling art? And can they prove it and not just say it, because frankly that's tough to believe... unless the art income is accompanied by social security, family help, etc., which I hope they would mention.
Who here is actually living a comfortable nomadic lifestyle funded by being a mobile personal assistant, or a blogger, or any other mobile job? Are they willing to openly talk about their income stream, how much, etc.? We all know the handful of really famous vandweller or DIY YouTubers and social media stars, including Bob Wells and the person you linked a video to, DIY Solar Power. He has half a million subscribers. I think the vast majority of people have zero chance of getting that kind of a social media following, just like the vast majority of people have zero chance of becoming a movie star.
In other words, I'm not convinced that people are actually making this lifestyle work with art or social media or businesses run out of their vans. I think that lifestyle is a bunch of glitz with no reality behind it, for the most part... simply because I don't know ANYONE thriving that way... but perhaps there are lots out there, and I am just not aware of them. The vast majority of people living the vanlife who have regular income seem to be getting pensions, social security, disability, public assistance, or conventional wage jobs (camp hosting, harvest, Wal-Mart, Amazon, etc.). Or they have a specialized skill like programming or stone masonry, etc.
