I mean, once I have enough money to retire, I'll retire, but I'll "keep working". The difference is that I'll be my own boss and manage my own time and lead my own projects. I can't imagine not doing this, since there's so much left to do.
I certainly wouldn't be working to make money or anything. I don't even etsy my CNC stuff (though I could) because I don't want to turn my hobbies into a "job"
It's really about whether you have customers or not, and what kinds of customers they are.
