5k a year? If you take this seriously, then making $5k a year is easy. Like anything, you put time and effort into something then it will pay off.
The other day, I was talking to someone about what I do. And I remember when I started, I was fustrated as hell. Because many were making the big bucks and was making close to nothing. But then I told him, you know what I really am? I told him I'm an internet farmer.
He laughed. And I said, back then I was planting all the seeds that will one day florish and I'll benefit from it. Sure enough that is the way it is. And that's what I do every single day. I maintain my cash crops and I plant more seeds for the future.
And with time I've seen it grow more and more. That's how you need to consider this. Don't expect to plan one litte seed (or arbi page) and expect to become a baller over night. NO way in hell is that going to happen.
You need to seed (and when I say seed, buy domains, setup sites, ppc, or whatever generates income) and see how it turns out. Sometimes the seeds are shit and no money is there. But other times you get a bumper crop. And also take into consideration, that this month or year might be a bumper crop, but next it will be shit (due to all kinds of variables google smartpricing, competition, etc).
So 5k a year easy. 5K a month more than possible. 5k a day, I know of many already there. So stop spreading the manure and start planting for a bumper crop.
PS: This analogy also works with weed (which I don't condone and is illegal

). But I was actually talking about internet marketing.
