Different things. I've had AdSense heavy site and sold that years ago, then built a SaaS and sold that. I do some e-commerce stuff, I have dozens of websites with different kind of affiliate, working on a SaaS right now and I too had some luck with crypto this year.

Basically years of building more or less successful side projects.

But to be fair no 2 years ago I was delivering paper ads for a few months, because a bunch of random projects surely aren't a sustainable income , always :)

Edit:// also it is actually cheaper living as I do than it was living down in the city. My house is old, we heat with wood only. Farming markets here are generally cheaper than supermarkets for quality meat and Vegs. The $500 overhead we pay for our car leasing we would not need otherwise is way less than what we save per square meter living so remote. And we need some extra space for the mentioned e-commerce
