those 150 projects that make you $12k / month aren't going to do so forever. I guess what it really comes down to is how much each project makes over its lifetime, relative to how much time you put into it. Pulling more numbers out of thin air, if it takes one day to push out a project making $1/day (a reasonable assumption, I think, once you've already made 100 of them or so), and if the project's useful lifetime is about 1 year, and if you work 200 days a year (so, 200 projects), that gives me $71000/year. You're not getting rich off this, but you can live comfortably almost anywhere in the world. Of course, the catch is that the projects should require zero maintenance, otherwise it adds up very quickly.
