It's like sustainable energy. First, it takes a lot to start up. You've got to be patient to work out all the kinks. But once it works, it works, and it's all uphill, right from the get go, no matter what.
As long as you're promoting content you believe in, and can always stand behind, you'll get there. But just like anything, you've got to work at it. I've been putting in huge hours just for the start up, and gaining online presence. I don't even have the content I want to be posting yet, but that will come eventually.
