Replacing my Income

So... I'm gonna try and keep track of the things I do to reach my goal. Which is to replace my current income, which is about $1200/wk, by using the internet. There must be a way to make money online that would be easy enough for a beginner to comprehend. I'm not too bad on a computer and don't have any trouble navigating my way around the net, but that's about as good as I get. So if there is anyone out there in the same boat as me who want to make a living online, let me know. Or anybody that can give me any tips!!
