I'm doing 99% of it myself, too. And 99% of the other 1% lol.

I'm running all four sites on my own, but really only building two sites out with (in the future) hundreds of articles. I wanted to spread the risk and hopefully accelerate my learning curve.

The other two sites I plan to build, age, and flip in the next year or two. Or, start to build in a year (so using it as a seed website of sorts).

Medium has been a lifesaver for me in the meantime!

But, you're so right: it's a whole lot of work to juggle it all.
