It's enough to pay for itself easily and pay for a vacation or two a year, for about 4 hours of work a week. If we really put effort in, it could replace our day jobs.
Where most people go wrong is their expectation. We expected this to fund a vacation and maybe car payments. That it's doing that is exactly right and we don't want to take it any further. If people had that view, instead of feeling like they have to make a billion dollars, I think side gigs would be a different beast entirely.
