It's particularly hard to stay motivated when revenue goes down for no reason. One would hope that with each successive hub, the numbers would only go up, but it's easy to forget that the internet is dynamic. The same hub that earned you a dollar today, could earn you nothing tomorrow. I would say to put the money aspect out of your head, but I think we all know that isn't possible. Rather, if you can't find any new ideas, try to hang out on the answers section or the forum section. Or if you're burnt out of the site entirely, take a few days off. The last thing you want to do is start hating this place because you feel obligated to come here.
