I kind of did this once! Essentially I got laid of from a job but happened to have a good money buffer and life was quite inexpensive at the time, so I just thought “fuck it” and went as long as I could without working, I made it about a year.
It was awesome! My mental health has never been better, I wrote most of a book, got pretty decent at Blender, started working on learning to make games… and then I had to go back to work and it all went to shit lol, that was several years ago and I haven’t touched any of it since.
I use addy.io to create aliases for different things, and then set up filters in Thunderbird to mark them as they come in so, for example, if I make an account at xyz.com and then I get a bunch of unrelated spam marked as coming from xyz.com, then I know they’ve been selling my info.
I probably have about a dozen or so aliases currently, but they’re pretty loosely organized.
