Go read Blind posts. You do have to be pretty good, but it's about where I'm at, and there are plenty others like me.
I'm aware that people make it. I'm aware that there's a "plenty", in a law of large numbers way that make it seems common even when it isn't. I guess my concern is that people talk about it like it should be the norm.
Actually these days there are many posts of people who are making double that.
